"Now if plurality and difference belong only to the appearance-form; if there is but one and the same Entity manifested in all living things: it follows that, when we obliterate the distinction between the ego and the non-ego, we are not the sport of an illusion. Rather are we so, when we maintain the reality of individuation, — a thing the Hindus call Maya, that is, a deceptive vision, a phantasma. The former theory we have found to be the actual source of the phaenomenon of Compassion; indeed Compassion is nothing but its translation into definite expression. This, therefore, is what I should regard as the metaphysical foundation of Ethics, and should describe it as the sense which identifies the ego with the non-ego, so that the individual directly recognises in another his own self, his true and very being. From this standpoint the profoundest teaching of theory pushed to its furthest limits may be shown in the end to harmonise perfectly with the rules of justice and loving-kindness, as exercised; and conversely, it will be clear that practical philosophers, that is, the upright, the beneficent, the magnanimous, do but declare through their acts the same truth as the man of speculation wins by laborious research … He who is morally noble, however deficient in mental penetration, reveals by his conduct the deepest insight, the truest wisdom; and puts to shame the most accomplished and learned genius, if the latter's acts betray that his heart is yet a stranger to this great principle, — the metaphysical unity of life."

“And O! how the mind is here washed clean of all its early ingrafted Jewish superstition! It is the most profitable and elevating reading which is possible in the world. It has been the solace of my life, and will be the solace of my death.”

“The New Testament, on the other hand, must be in some way traceable to an Indian source: its ethical system, its ascetic view of morality, its pessimism, and its Avatar, are all thoroughly Indian. It is its morality which places it in a position of such emphatic and essential antagonism to the Old Testament, so that the story of the Fall is the only possible point of connection between the two.”

“This art is music. It stands quite apart from all the others. In it we do not recognize the copy, the repetition, of any Idea of the inner nature of the world. Yet it is such a great and exceedingly fine art, its effect on man's innermost nature is so powerful, and it is so completely and profoundly understood by him in his innermost being as an entirely universal language, whose distinctness surpasses even that of the world of perception itself, that in it we certainly have to look for more than that exercitium arithmeticae occultum nescientis se numerare animi [exercise in arithmetic in which the mind does not know it is counting] which Leibniz took it to be.”

“And O! how the mind is here washed clean of all its early ingrafted Jewish superstition ! It is the most profitable and elevating reading which is possible in the world. It has been the solace of my life, and will be the solace of my death.”

“Change alone is eternal, perpetual, immortal.”

“In an essay on ‘“The Christian System,” he argued that the visions of the Old and New Testament are so unalike that the latter “‘must be in some way traceable to an Indian source: its ethical system, its ascetic view of morality, its pessimism and its Avatar, are all thoroughly Indian.””
