CHAPTER I
That Art Thou
IN STUDYING the Perennial Philosophy we can begin either at the bottom, with practice and morality; or at the top, with a consideration of metaphysical truths; or, finally, in the middle, at the focal point where mind and matter, action and thought have their meeting place in human psychology.
The lower gate is that preferred by strictly practical teachers—men who, like Gautama Buddha, have no use for speculation and whose primary concern is to put out in men’s hearts the hideous fires of greed, resentment and infatuation. Through the upper gate go those whose vocation it is to think and speculate—the born philosophers and theologians. The middle gate gives entrance to the exponents of what has been called “spiritual religion”—the devout contemplatives of India, the Sufis of Islam, the Catholic mystics of the later Middle Ages, and, in the Protestant tradition, such men as Denk and Franck and Castellio, as Everard and John Smith and the first Quakers and William Law.
It is through this central door, and just because it is central, that we shall make our entry into the subject matter of this book. The psychology of the Perennial Philosophy has its source in metaphysics and issues logically in a characteristic way of life and system of ethics. Starting from this midpoint of doctrine, it is easy for the mind to move in either direction.
In the present section we shall confine our attention to but a single feature of this traditional psychology—the most important, the most emphatically insisted upon by all exponents of the Perennial Philosophy and, we may add, the least psychological. For the doctrine that is to be illustrated in this section belongs to autology rather than psychology—to the science, not of the personal ego, but of that eternal Self in the depth of particular, individualized selves, and identical with, or at least akin to, the divine Ground. Based upon the direct experience of those who have fulfilled the necessary conditions of such knowledge, this teaching is expressed most succinctly in the Sanskrit formula, tat tvam asi (“That art thou”); the Atman, or immanent eternal Self, is one with Brahman, the Absolute Principle of all existence; and the last end of every human being is to discover the fact for himself, to find out Who he really is.
Only the transcendent, the completely other, can be immanent without being modified by the becoming of that in which it dwells. The Perennial Philosophy teaches that it is desirable and indeed necessary to know the spiritual Ground of things, not only within the soul, but also outside in the world and, beyond world and soul, in its transcendent otherness—“in heaven.”
This extract seems to contradict what was said above; but the contradiction is not a real one. God within and God without—these are two abstract notions, which can be entertained by the understanding and expressed in words. But the facts to which these notions refer cannot be realized and experienced except in “the deepest and most central part of the soul.” And this is true no less of God without than of God within. But though the two abstract notions have to be realized (to use a spatial metaphor) in the same place, the intrinsic nature of the realization of God within is qualitatively different from that of the realization of God without, and each in turn is different from that of the realization of the Ground as simultaneously within and without—as the Self of the perceiver and at the same time (in the words of the Bhagavad-Gita) as “That by which all this world is pervaded.”
The man who wishes to know the “That” which is “thou” may set to work in any one of three ways. He may begin by looking inwards into his own particular thou and, by a process of “dying to self”—self in reasoning, self in willing, self in feeling—come at last to a knowledge of the Self, the Kingdom of God that is within. Or else he may begin with the thous existing outside himself, and may try to realize their essential unity with God and, through God, with one another and with his own being. Or, finally (and this is doubtless the best way), he may seek to approach the ultimate That both from within and from without, so that he comes to realize God experimentally as at once the principle of his own thou and of all other thous, animate and inanimate. The completely illuminated human being knows, with Law, that God “is present in the deepest and most central part of his own soul”; but he is also and at the same time one of those who, in the words of Plotinus,
It is from the more or less obscure intuition of the oneness that is the ground and principle of all multiplicity that philosophy takes its source. And not alone philosophy, but natural science as well. All science, in Meyerson’s phrase, is the reduction of multiplicities to identities. Divining the One within and beyond the many, we find an intrinsic plausibility in any explanation of the diverse in terms of a single principle.
The philosophy of the Upanishads reappears, developed and enriched, in the Bhagavad-Gita and was finally systematized, in the ninth century of our era, by Shankara. Shankara’s teaching (simultaneously theoretical and practical, as is that of all true exponents of the Perennial Philosophy) is summarized in his versified treatise, Viveka-Chudarnani (“The Crest-Jewel of Wisdom”). All the following passages are taken from this conveniently brief and untechnical work.
In the Taoist formulations of the Perennial Philosophy there is an insistence, no less forcible than in the Upanishads, the Gita and the writings of Shankara, upon the universal immanence of the transcendent spiritual Ground of all existence. What follows is an extract from one of the great classics of Taoist literature, the Book of Chuang Tzu, most of which seems to have been written around the turn of the fourth and third centuries B. C.
From Taoism we pass to that Mahayana Buddhism which, in the Far East, came to be so closely associated with Taoism, borrowing and bestowing until the two came at last to be fused in what is known as Zen. The Lankavatara Sutra, from which the following extract is taken, was the scripture which the founder of Zen Buddhism expressly recommended to his first disciples.
I am not competent, nor is this the place to discuss the doctrinal differences between Buddhism and Hinduism. Let it suffice to point out that, when he insisted that human beings are by nature “non-Atman,” the Buddha was evidently speaking about the personal self and not the universal Self. The Brahman controversialists, who appear in certain of the Pali scriptures, never so much as mention the Vedanta doctrine of the identity of Atman and Godhead and the non-identity of ego and Atman. What they maintain and Gautama denies is the substantial nature and eternal persistence of the individual psyche. “As an unintelligent man seeks for the abode of music in the body of the lute,...
