The reality of a person is his/her thought

The reality of man is his thought, not his material body. The thought force and the animal force are partners. .... If a man's thought is constantly aspiring towards heavenly subjects then does he become saintly; if on the other hand his thought does not soar, but is directed downwards to centre itself upon the things of this world, he grows more and more material until he arrives at a state little better than that of a mere animal.

The reason God’s Prophets “have appeared in this world”

The Prophets have appeared in this world with the mission that human souls may become the expressions of the Merciful, that they may be educated and developed, attain to love and amity and establish peace and agreement.

 - ‘Abdu’l-Baha  (From a talk given on 21 April 1912 in Washington D.C.; ‘The Promulgation of Universal Peace: Talks Delivered by ‘Abdu’l-Bahá during His Visit to the United States and Canada in 1912’)

“mental faculties... are in truth of the inherent properties of the soul”

Now concerning mental faculties, they are in truth of the inherent properties of the soul, even as the radiation of light is the essential property of the sun.

- ‘Abdu’l-Baha  (‘Tablet to August Forel’)

“It is not merely material well-being that people need”

In our concern for such immediate obvious calls upon our succor we must not allow ourselves to forget the continuing, appalling burden of suffering under which millions of human beings are always groaning -- a burden which they have borne for century upon century and which it is the mission of Bahá'u'lláh to lift at last. The principal cause of this suffering, which one can witness wherever one turns, is the corruption of human morals and the prevalence of prejudice, suspicion, hatred, untrustworthiness, selfishness and tyranny among men. It is not merely material well-being that people need. What they desperately need is to know how to live their lives -- they need to know who they are, to what purpose they exist, and how they should act towards one another; and, once they know the answers to these questions they need to be helped to gradually apply these answers to everyday behavior. It is to the solution of this basic problem of mankind that the greater part of all our energy and resources should be directed. There are mighty agencies in this world, governments, foundations, institutions of many kinds with tremendous financial resources which are working to improve the material lot of human beings. Anything we Bahá'ís could add to such resources in the way of special funds or contributions would be a negligible drop in the ocean. However, alone among men we have the divinely-given remedy for the real ills of mankind; no one else is doing or can do this most important work.

Value of intuition as a source of guidance

With regard to your question as to the value of intuition as a source of guidance for the individual: implicit faith in our intuitive powers is unwise, but through daily prayer and sustained effort one can discover, though not always and fully, God’s will intuitively. Under no circumstances, however, can a person be absolutely certain that he is recognizing God’s will, through the exercise of his intuition. It often happens that the latter results in completely misrepresenting the truth, and thus becomes a source of error rather than of guidance.

The Cause of God is like a house

The Cause of God is like a house. As long as man has not entered therein he does not know what it contains. In the house there are many precious jewels, many rare objects the like of which cannot be found anywhere in this world. But the men in the street may pass by the house a 1000 times and know nothing about it. Only the one who has the key can enter. That key is the love of God. 

- 'Abdu'l-Baha  (Words of ‘Abdu’l-Baha recorded by Ahmad Sohrab, ‘Abdu'l-Baha in Britain, 1913’)

The source of evil thoughts

Question: What is the source of evil thoughts that disturb those who do not wish to entertain them?

Answer [by 'Abdu'l-Baha]: “They come from other minds; they are reflected. One should not become a mirror for them - to reflect them; neither should one try to control them, for this is impossible; it only aggravates the difficulty, causing more to appear.

One should constantly turn the mirror of his heart squarely toward God so that the Light of the Sun of Truth may be reflected there.

This is the only cure for attacks of evil thoughts. The face of the mirror should be turned toward God, and the back of the mirror toward the evil thoughts.”

-' Abdu'l-Baha  (From a table talk by ‘Abdu’l-Baha, ‘Daily Lessons Received at Akka January 1908”, by Helen Goodall and Ella Goodall Cooper)

"Nature is God's Will and is its expression in and through the contingent world.”

Say: Nature in its essence is the embodiment of My Name, the Maker, the Creator. Its manifestations are diversified by varying causes, and in this diversity there are signs for men of discernment. Nature is God's Will and is its expression in and through the contingent world. It is a dispensation of Providence ordained by the Ordainer, the All-Wise. Were anyone to affirm that it is the Will of God as manifested in the world of being, no one should question this assertion. It is endowed with a power whose reality men of learning fail to grasp. Indeed a man of insight can perceive naught therein save the effulgent splendour of Our Name, the Creator. Say: This is an existence which knoweth no decay, and Nature itself is lost in bewilderment before its revelations, its compelling evidences and its effulgent glory which have encompassed the universe. 

- Baha'u'llah  ('Tablets of Baha'u'llah revealed after the Kitab-i-Aqdas')

“The Prophets of God have come to show man the way of righteousness in order that he may not follow his own natural impulse”

In the world of existence the animal is a captive of nature. Its actions are according to the exigencies and requirements of nature. It has no consideration or consciousness of good and evil. It simply follows its natural instinct and inclination. The Prophets of God have come to show man the way of righteousness in order that he may not follow his own natural impulse but govern his action by the light of Their precept and example. According to Their teachings he should do that which is found to be praiseworthy by the standard of reason and judgment of intellect, even though it be opposed to his natural human inclination; and he should not do that which is found to be unworthy by that same standard, even though it be in the direction of his natural impulse and desire. Therefore, man must follow and manifest the attributes of the Merciful. 

- ‘Abdu’l-Baha  (From a talk given on 21 April 1912 in Washington D.C.; ‘The Promulgation of Universal Peace: Talks Delivered by 'Abdu'l-Bahá during His Visit to the United States and Canada in 1912’)

Moral life vs. Immorality

Moral life consists in the government of one's self. Immortality is government of a human soul by the Divine Will.

The “rights of woman and her equality with man”

Today questions of the utmost importance are facing humanity, questions peculiar to this radiant century.... One of these questions concerns the rights of woman and her equality with man. In past ages it was held that woman and man were not equal -- that is to say, woman was considered inferior to man, even from the standpoint of her anatomy and creation. She was considered especially inferior in intelligence, and the idea prevailed universally that it was not allowable for her to step into the arena of important affairs. In some countries man went so far as to believe and teach that woman belonged to a sphere lower than human. But in this century, which is the century of light and the revelation of mysteries, God is proving to the satisfaction of humanity that all this is ignorance and error; nay, rather, it is well established that mankind and womankind as parts of composite humanity are coequal and that no difference in estimate is allowable, for all are human. The conditions in past centuries were due to woman's lack of opportunity. She was denied the right and privilege of education and left in her undeveloped state. Naturally, she could not and did not advance. In reality, God has created all mankind, and in the estimation of God there is no distinction as to male and female. The one whose heart is pure is acceptable in His sight, be that one man or woman. God does not inquire, "Art thou woman or art thou man?" He judges human actions. If these are acceptable in the threshold of the Glorious One, man and woman will be equally recognized and rewarded.

The “sovereign remedy and mightiest instrument for the healing of all the world”

That which the Lord hath ordained as the sovereign remedy and mightiest instrument for the healing of all the world is the union of all its peoples in one universal Cause, one common Faith. This can in no wise be achieved except through the power of a skilled, an all-powerful and inspired Physician. This, verily, is the truth, and all else naught but error. Each time that Most Mighty Instrument hath come, and that Light shone forth from the Ancient Dayspring, He was withheld by ignorant physicians who, even as clouds, interposed themselves between Him and the world. It failed, therefore, to recover, and its sickness hath persisted until this day. They indeed were powerless to protect it, or to effect a cure, whilst He Who hath been the Manifestation of Power amongst men was withheld from achieving His purpose, by reason of what the hands of the ignorant physicians have wrought. 

- Baha'u'llah  (From a Tablet to Queen Victoria; ‘The Summons of the Lord of Hosts’)

Prophets are like perfect Mirrors reflecting the perfections of God

… the perfect man, the Prophet, is one who is transfigured, one who has the purity and clearness of a perfect mirror -- one who reflects the Sun of Truth. Of such a one -- of such a Prophet and Messenger -- we can say that the Light of Divinity with the heavenly Perfections dwells in him.

If we claim that the sun is seen in the mirror, we do not mean that the sun itself has descended from the holy heights of his heaven and entered into the mirror! This is impossible. The Divine Nature is seen in the Manifestations and its Light and Splendor are visible in extreme glory. 

- ‘Abdu'l-Baha  (From a talk, ''Abdu'l-Baha in London’)

The beginning of creation…

As regards thine assertions about the beginning of creation, this is a matter on which conceptions vary by reason of the divergences in men’s thoughts and opinions. Wert thou to assert that it hath ever existed and shall continue to exist, it would be true; or wert thou to affirm the same concept as is mentioned in the sacred Scriptures, no doubt would there be about it, for it hath been revealed by God, the Lord of the worlds. Indeed He was a hidden treasure. This is a station that can never be described nor even alluded to. And in the station of ‘I did wish to make Myself known’, God was, and His creation had ever existed beneath His shelter from the beginning that hath no beginning, apart from its being preceded by a Firstness which cannot be regarded as firstness and originated by a Cause inscrutable even unto all men of learning.

That which hath been in existence had existed before, but not in the form thou seest today. The world of existence came into being through the heat generated from the interaction between the active force and that which is its recipient. These two are the same, yet they are different. Thus doth the Great Announcement inform thee about this glorious structure. Such as communicate the generating influence and such as receive its impact are indeed created through the irresistible Word of God which is the Cause of the entire creation, while all else besides His Word are but the creatures and the effects thereof. Verily thy Lord is the Expounder, the All-Wise.

The “’two wings’ of the soul”

Regarding the “two wings” of the soul: These signify wings of ascent. One is the wing of knowledge, the other of faith, as this is the means of the ascent of the human soul to the lofty station of divine perfections…
