“The union of the mathematician with the poet, fervor with measure, passion with correctness, this surely is the ideal.”

He stated when he deviated from the Valmiki Ramayana epic story and was criticized for the changes made.

Context: He who is called Brahman by the jnanis is known as Atman by the yogis and as Bhagavan by the bhaktas. The same brahmin is called priest, when worshipping in the temple, and cook, when preparing a meal in the kitchen. The jnani, following the path of knowledge, always reason about the Reality saying, "not this, not this." Brahman is neither "this" nor "that"; It is neither the universe nor its living beings. Reasoning in this way, the mind becomes steady. Finally it disappears and the aspirant goes into samadhi. This is the Knowledge of Brahman. It is the unwavering conviction of the jnani that Brahman alone is real and the world is illusory. All these names and forms are illusory, like a dream. What Brahman is cannot be described. One cannot even say that Brahman is a Person. This is the opinion of the jnanis, the followers of Vedanta. But the bhaktas accept all the states of consciousness. They take the waking state to be real also. They don't think the world to be illusory, like a dream. They say that the universe is a manifestation of the God's power and glory. God has created all these — sky, stars, moon, sun, mountains, ocean, men, animals. They constitute His glory. He is within us, in our hearts. Again, He is outside. The most advanced devotees say that He Himself has become all this — the 24 cosmic principles, the universe, and all living beings. The devotee of God wants to eat sugar, and not become sugar. (All laugh.) Do you know how a lover of God feels? His attitude is: "O God, Thou art the Master, and I am Thy servant. Thou art the Mother, and I Thy child." Or again: "Thou art my Father and Mother. Thou art the Whole, and I am a part." He does not like to say, "I am Brahman." They yogi seeks to realize the Paramatman, the Supreme Soul. His ideal is the union of the embodied soul and the Supreme Soul. He withdraws his mind from sense objects and tries to concentrate on the Paramatman. Therefore, during the first stage of his spiritual discipline, he retires into solitude and with undivided attention practices meditation in a fixed posture.
But the reality is one and the same; the difference is only in name. He who is Brahman is verily Atman, and again, He is the Bhagavan. He is Brahman to the followers of the path of knowledge, Paramatman to the yogis, and Bhagavan to the lovers of God.

Context: What does the Scripture mean when it tells us of the body of one man so extended in space that all can kill him? We must understand these words of ourselves, of our Church, or the body of Christ. For Jesus Christ is one man, having a Head and a body. The Saviour of the body and the members of the body are two in one flesh, and in one voice, and in one passion, and, when iniquity shall have passed away, in one repose.
And so the passion of Christ is not in Christ alone; and yet the passion of Christ is in Christ alone. For if in Christ you consider both the Head and the body, the Christ’s passion is in Christ alone; but if by Christ you mean only the Head, then Christ’s passion is not in Christ alone. Hence if you are in the members of Christ, all you who hear me, and even you who hear me not (though you do hear, if you are united with the members of Christ), whatever you suffer at the hands of those who are no among the members of Christ, was lacking to the sufferings of Christ. It is added precisely because it was lacking. You fill up the measure; you do not cause it to overflow. You will suffer just so much as must be added of your sufferings to the complete passion of Christ, who suffered as our Head and who continues to suffer in His members, that is, in us. Into this common treasury each pays what he owes, and according to each one’s ability we all contribute our share of suffering. The full measure of the Passion will not be attained until the end of the world.
