Abstract

According to the Hindu tradition, the origin of the various philosophical ideas that were developed in the philosophical systems lies in the Vedas, a body of texts that seem to have been composed around two thousand years Before the Common Era (BCE). While the Vedas contain a myriad of different themes, ranging from hymns for deities and rules of fire sacrifices to music and magic, there is no doubt that one finds in them an exemplary spirit of inquiry into “the one being” (ekam sat) that underlies the diversity of empirical phenomena, and into the origin of all things. (“Was there being or non‐being at the beginning?”) One finds also predelineations of such concepts of ṛta (truth or moral order), karma and the afterlife, and the three qualities (or guṇas: sattva, rajas, and tamas) constituting nature (prakṛti). It is in the Upaniṣads (a group of texts composed after the Vedas and ranging from 1000 bce to the time of Gautama, the Buddha), that the thinking, while still retaining its poetic flavor, develops a more strictly philosophical character. While still concerned with many different themes belonging to cosmology (“How did the one being become many?”) and psychology (“What does the empirical person consist of?”), the Upaniṣads contain attempts to reinterpret, in symbolic terms, the elaborate Vedic sacrifices, and to defend, in many different ways, one central philosophical thesis – that is, the identity of Brahman (the highest and the greatest, the source of all things) and ātman (the self within each person). With this last identification, a giant step was taken by the authors of the Upaniṣads, a step that was decisive for the development of Indian philosophy. The Vedas had already decided, famously in the Nāsadiya Sukata, that at the beginning of things there must have been being and not non‐being (for something cannot come out of nothing); now this primeval being was said to be the same as the spirit within. The highest wisdom was intuitively realizing this identity of subject and object (tat tvarn asi). How to know it was the issue. Suggestions ranged from contemplative meditation to austere self‐mortification. The idea of yoga and a picture of the yogin make their appearance – possibly having a different origin – and blend with the central thesis of the Upaniṣads. If the reality underlying outer appearance is the universal spirit within, is then the world merely phenomenal appearance (like the magician's creation, māyā), or is the brahman‐ātman to be construed as the indwelling spirit of all things? These become the leading disputational questions amongst the commentators on the Upaniṣads, and amongst the various schools of the Vedānta philosophy.
