In such statements the Gita distills the essence of the Upanishads, not piecemeal but comprehensively, offering their lofty insights as a manual not of philosophy but of everyday human activity – a handbook of the Perennial Philosophy unique in world history.
THE UPANISHADIC BACKGROUND
The Gita, naturally enough, takes for granted that its audience is familiar with the basic ideas of Hindu religious thought, almost all of which can be found in the Upanishads. It also uses some technical vocabulary from yoga psychology. All this needs to be explained in contemporary terms if the modern reader is to grasp what is essential and timeless in the Gita’s message and not get bogged down in strange terminology.
First, however, the non-Hindu faces a third obstacle: the multiplicity of names used for aspects of God. From the earliest times, Hinduism has proclaimed one God while accommodating worship of him (or her, for to millions God is the Divine Mother) in many different names. “Truth is one,” says a famous verse of the Rig Veda; “people call it by various names.” Monastic devotees might find that Shiva embodies the austere detachment they seek; devotees who want to live “in the world,” partaking of its innocent pleasures but devoted to service of their fellow creatures, might find in Krishna the perfect incarnation of their ideals. In every case, this clothing of the Infinite in human form serves to focus a devotee’s love and to provide an inspiring ideal. But whatever form is worshipped, it is only an aspect of the same one God.
In the Gita – in fact, virtually everywhere in Hindu myth and scripture – we also encounter “the gods” in the plural. These are the devas, deities which seem to have come in with the Aryans and which have recognizable counterparts in other Aryan-influenced cultures: Indra, god of war and storm; Varuna, god of waters and a moral overseer; Agni, god of fire, the Hermes-like intermediary between heaven and earth; and so on. The Gita refers to the devas as being worshipped by those who want to propitiate natural and supernatural powers, in much the same way that ancestors were worshipped. In modern terms, they can best be understood as personifying the forces of nature.
This question out of the way, we can proceed to the Upanishadic background the Gita assumes.
Atman and Brahman
The Upanishads are not systematic philosophy; they are more like ecstatic slide shows of mystical experience – vivid, disjointed, stamped with the power of direct personal encounter with the divine. If they seem to embrace contradictions, that is because they do not try to smooth over the seams of these experiences. They simply set down what the rishis saw, viewing the ultimate reality from different levels of spiritual awareness, like snapshots of the same object from different angles: now seeing God as utterly transcendent, for example, now seeing God as immanent as well. These differences are not important, and the Upanishads agree on their central ideas: Brahman, the Godhead; Atman, the divine core of personality; dharma, the law that expresses and maintains the unity of creation; karma, the web of cause and effect; samsara, the cycle of birth and death; moksha, the spiritual liberation that is life’s supreme goal.
Even while ancient India was making breakthroughs in the natural sciences and mathematics, the sages of the Upanishads were turning inward to analyze the data that nature presents to the mind. Penetrating below the senses, they found not a world of solid, separate objects but a ceaseless process of change – matter coming together, dissolving, and coming together again in a different form. Below this flux of things with “name and form,” however, they found something changeless: an infinite, indivisible reality in which the transient data of the world cohere. They called this reality Brahman: the Godhead, the divine ground of existence.
This analysis of the phenomenal world tallies well enough with contemporary physics. A physicist would remind us that the things we see “out there” are not ultimately separate from each other and from us; we perceive them as separate because of the limitations of our senses. If our eyes were sensitive to a much finer spectrum, we might see the world as a continuous field of matter and energy. Nothing in this picture resembles a solid object in our usual sense of the word. “The external world of physics,” wrote Sir Arthur Eddington, “has thus become a world of shadows. In removing our illusions we remove the substance, for indeed we have seen that substance is one of the greatest of our illusions.” Like the physicists, these ancient sages were seeking an invariant. They found it in Brahman.
In examining our knowledge of ourselves, the sages made a similar discovery. Instead of a single coherent personality, they found layer on layer of components – senses, emotions, will, intellect, ego – each in flux. At different times and in different company, the same person seems to have different personalities. Moods shift and flicker, even in those who are emotionally stable; desires and opinions change with time. Change is the nature of the mind. The sages observed this flow of thoughts and sensations and asked, “Then where am I?” The parts do not add up to a whole; they just flow by. Like physical phenomena, the mind is a field of forces, no more the seat of intelligence than radiation or gravity is. Just as the world dissolves into a sea of energy, the mind dissolves into a river of impressions and thoughts, a flow of fragmentary data that do not hold together.
Western philosophers have reasoned their way to a similar conclusion, but with them it was an intellectual exercise. David Hume confesses that whenever he was forced to conclude that his empirical ego was insubstantial, he went out for a walk, had a good dinner, and forgot all about it. For these ancient sages, however, these were not logical conclusions but personal discoveries. They were actually exploring the mind, testing each level of awareness by withdrawing consciousness to the level below. In profound meditation, they found, when consciousness is so acutely focused that it is utterly withdrawn from the body and mind, it enters a kind of singularity in which the sense of a separate ego disappears. In this state, the supreme climax of meditation, the seers discovered a core of consciousness beyond time and change. They called it simply Atman, the Self.
I have described the discovery of Atman and Brahman – God immanent and God transcendent – as separate, but there is no real distinction. In the climax of meditation, the sages discovered unity: the same indivisible reality without and within. It was advaita, “not two.” The Chandogya Upanishad says epigrammatically, Tat tvam asi: “Thou art That.” Atman is Brahman: the Self in each person is not different from the Godhead.
Nor is it different from person to person. The Self is one, the same in every creature. This is not some peculiar tenet of the Hindu scriptures; it is the testimony of everyone who has undergone these experiments in the depths of consciousness and followed them through to the end. Here is Ruysbroeck, a great mystic of medieval Europe; every word is most carefully chosen:
The image of God is found essentially and personally in all mankind. Each possesses it whole, entire and undivided, and all together not more than one alone. In this way we are all one, intimately united in our eternal image, which is the image of God and the source in us of all our life.
Maya
In the unitive experience, every trace of separateness disappears; life is a seamless whole. But the body cannot remain in this state for long. After a while, awareness of mind and body returns, and then the conventional world of multiplicity rushes in again with such vigor and vividness that the memory of unity, though stamped with reality, seems as distant as a dream. The unitive state has to be entered over and over until a person is established in it. But once established, even in the midst of ordinary life, one sees the One underlying the many, the Eternal beneath the ephemeral.
What is it that makes undivided reality appear to be a world of separate, transient objects? What makes each of us believe that we are the body rather than our own Self? The sages answered with a story still told after thousands of years. Imagine, they said, a man dreaming that he is being attacked by a tiger. His pulse will race, his fists will clench, his forehead will be wet with the dew of fear – all just as if the attack were real. He will be able to describe the look of his tiger, the way he smelled, the sound of his roar. For him the tiger is real, and in a sense he is not wrong: the evidence he has is not qualitatively different
