"magical force" and "great," transition between which is rather easy. Even when the sacrifices began to be replaced by meditations, the old belief in the power of the sacrifices still remained, and as a result of that we find that in many passages of the Upani@sads people are thinking of meditating upon this great force "Brahman" as being identified with diverse symbols, natural objects, parts and functions of the body. When the main interest of sacrifice was transferred from its actual performance in the external world to certain forms of meditation, we find that the understanding of particular allegories of sacrifice having a relation to particular kinds of bodily functions was regarded as Brahman, without a knowledge of which nothing could be obtained. The fact that these allegorical interpretations of the Pañcâgnividyâ are so much referred to in the Upani@sads as a secret doctrine, shows that some people came to think that the real efficacy of sacrifices depended upon such meditations. When the sages rose to the culminating conception, that he is really ignorant who thinks the gods to be different from him, they thought that as each man was nourished by many beasts, so the gods were nourished by each man, and as it is unpleasant for a man if any of his beasts are taken away, so it is unpleasant for the gods that men should know this great truth. [Footnote ref 1]. In the Kena we find it indicated that all the powers of the gods such as that of Agni (fire) to burn, Vâyu (wind) to blow, depended upon Brahman, and that it is through Brahman that all the gods and all the senses of man could work. The whole process of Upani@sad thought shows that the magic power of sacrifices as associated with @Rta (unalterable law) was being abstracted from the sacrifices and conceived as the supreme power. There are many stories in the Upani@sads of the search after the nature of this great power the Brahman, which was at first only imperfectly realized. They identified it with the dominating power of the natural objects of wonder, the sun, the moon, etc. with bodily and mental functions and with various symbolical representations, and deluded themselves for a time with the idea that these were satisfactory. But as these were gradually found inadequate, they came to the final solution, and the doctrine of the inner self of man as being the highest truth the Brahman originated. ___________________________________________________________________ [Footnote 1: B@rh.
