By Swami Harshananda
Śāṇḍilyavidyā literally means ‘science taught by Śāṇḍilya’.
In the Chāndogya Upaniṣad Brahman is described as tajjalān. A description of this Brahman, both as the transcendent and the immanent reality followed by the fruits of meditating on him are given here. This knowledge is known as Śāndilyavidyā as it was first taught by the sage Śāṇḍilya.
