According to the Vedic version there is no existence beyond Brahman. Sarvaṁ khalv idaṁ brahma (Chāndogya Upaniṣad 3.14.1). It is stated also in the Viṣṇu Purāṇa that whatever we see is parasya brahmaṇaḥ śaktiḥ; everything is an expansion of the energy of the Supreme Absolute Truth, Brahman. When Brahman is mixed with the three qualities goodness, passion and ignorance, there results the material expansion, which is sometimes called saguṇa Brahman and which consists of these twenty-five elements. In the nirguṇa Brahman, where there is no material contamination, or in the spiritual world, the three modes — goodness, passion and ignorance — are not present. Where nirguṇa Brahman is found, simple unalloyed goodness prevails. Saguṇa Brahman is described by the Sāṅkhya system of philosophy as consisting of twenty-five elements, including the time factor (past, present and future).
