"Bahá’u’lláh has proclaimed the oneness of the world of humanity."

"But there is need of a superior power to overcome human prejudices, a power which nothing in the world of mankind can withstand and which will overshadow the effect of all other forces at work in human conditions. That irresistible power is the love of God. It is my hope and prayer that it may destroy the prejudice of this one point of distinction between you and unite you all permanently under its hallowed protection. Bahá’u’lláh has proclaimed the oneness of the world of humanity. He has caused various nations and divergent creeds to unite. He has declared that difference of race and color is like the variegated beauty of flowers in a garden. If you enter a garden, you will see yellow, white, blue, red flowers in profusion and beauty—each radiant within itself and although different from the others, lending its own charm to them. Racial difference in the human kingdom is similar. If all the flowers in a garden were of the same color, the effect would be monotonous and wearying to the eye."

"loose thy soul from the prison of self..."

"O MY SERVANT! Free thyself from the fetters of this world, and loose thy soul from the prison of self. Seize thy chance, for it will come to thee no more."

-Bahá'u'lláh, The Hidden Words of Bahá’u’lláh, #40 Persian

"That which contains is superior to that which is contained."

"In the Old Testament we read that God said, ‘Let us make man in Our own image’. In the Gospel, Christ said, ‘I am in the Father, and the Father in Me’. In the Qur’án, God says, ‘Man is my Mystery and I am his’. Bahá’u’lláh writes that God says, ‘Thy heart is My home; purify it for My descent. Thy spirit is My place of revelation; cleanse it for My manifestation’.
All these sacred words show us that man is made in God’s image: yet the Essence of God is incomprehensible to the human mind, for the finite understanding cannot be applied to this infinite Mystery. God contains all: He cannot be contained. That which contains is superior to that which is contained. The whole is greater than its parts."
-'Abdu'l-Baha, Paris Talks, p. 23-24

"The whole of mankind is in the grip of manifold ills. "

"The Prophets of God should be regarded as physicians whose task is to foster the well-being of the world and its peoples, that, through the spirit of oneness, they may heal the sickness of a divided humanity. To none is given the right to question their words or disparage their conduct, for they are the only ones who can claim to have understood the patient and to have correctly diagnosed its ailments. No man, however acute his perception, can ever hope to reach the heights which the wisdom and understanding of the Divine Physician have attained. Little wonder, then, if the treatment prescribed by the physician in this day should not be found to be identical with that which he prescribed before. How could it be otherwise when the ills affecting the sufferer necessitate at every stage of his sickness a special remedy? In like manner, every time the Prophets of God have illumined the world with the resplendent radiance of the Day Star of Divine knowledge, they have invariably summoned its peoples to embrace the light of God through such means as best befitted the exigencies of the age in which they appeared. They were thus able to scatter the darkness of ignorance, and to shed upon the world the glory of their own knowledge. It is towards the inmost essence of these Prophets, therefore, that the eye of every man of discernment must be directed, inasmuch as their one and only purpose hath always been to guide the erring, and give peace to the afflicted…. These are not days of prosperity and triumph. The whole of mankind is in the grip of manifold ills. Strive, therefore, to save its life through the wholesome medicine which the almighty hand of the unerring Physician hath prepared."
-Baha'u'llah, Gleanings from the Writings of Baha'u'llah, p. 80-81

"...traverse a realm which lieth hidden in the innermost reality of this world."

"As to thy question concerning the worlds of God. Know thou of a truth that the worlds of God are countless in their number, and infinite in their range. None can reckon or comprehend them except God, the All-Knowing, the All-Wise. Consider thy state when asleep. Verily, I say, this phenomenon is the most mysterious of the signs of God amongst men, were they to ponder it in their hearts. Behold how the thing which thou hast seen in thy dream is, after a considerable lapse of time, fully realized. Had the world in which thou didst find thyself in thy dream been identical with the world in which thou livest, it would have been necessary for the event occurring in that dream to have transpired in this world at the very moment of its occurrence. Were it so, you yourself would have borne witness unto it. This being not the case, however, it must necessarily follow that the world in which thou livest is different and apart from that which thou hast experienced in thy dream. This latter world hath neither beginning nor end. It would be true if thou wert to contend that this same world is, as decreed by the All-Glorious and Almighty God, within thy proper self and is wrapped up within thee. It would equally be true to maintain that thy spirit, having transcended the limitations of sleep and having stripped itself of all earthly attachment, hath, by the act of God, been made to traverse a realm which lieth hidden in the innermost reality of this world. Verily I say, the creation of God embraceth worlds besides this world, and creatures apart from these creatures. In each of these worlds He hath ordained things which none can search except Himself, the All-Searching, the All-Wise."
-Baha'u'llah, Gleanings from the Writings of Baha'u'llah, p. 151-153

"But the question may be asked: How shall we know God?"

"But the question may be asked: How shall we know God? We know Him by His attributes. We know Him by His signs. We know Him by His names. We know not what the reality of the sun is, but we know the sun by the ray, by the heat, by its efficacy and penetration. We recognize the sun by its bounty and effulgence, but as to what constitutes the reality of the solar energy, that is unknowable to us. The attributes characterizing the sun, however, are knowable. If we wish to come in touch with the reality of Divinity, we do so by recognizing its phenomena, its attributes and traces, which are widespread in the universe. All things in the world of phenomena are expressive of that one reality. Its lights are shining, its heat is manifest, its power is expressive, and its education, or training, resplendent everywhere. What proof could there be greater than that of its functioning or its attributes which are manifest?"

"God has not intended man to imitate blindly his fathers and ancestors."

"Furthermore, know ye that God has created in man the power of reason, whereby man is enabled to investigate reality. God has not intended man to imitate blindly his fathers and ancestors. He has endowed him with mind, or the faculty of reasoning, by the exercise of which he is to investigate and discover the truth, and that which he finds real and true he must accept. He must not be an imitator or blind follower of any soul. He must not rely implicitly upon the opinion of any man without investigation; nay, each soul must seek intelligently and independently, arriving at a real conclusion and bound only by that reality. The greatest cause of bereavement and disheartening in the world of humanity is ignorance based upon blind imitation. It is due to this that wars and battles prevail; from this cause hatred and animosity arise continually among mankind."
