उपनिषद पुस्तकें हैं-

'उपनिषद' दर्शन पर आधारित पुस्तकें हैं। इन्हें वेदांत भी कहा जाता है।

The Upanishad literature is not a religious scripture but represents a philosophy for all times and for all. The philosophy of Upanishads does not oppose any school of thought, religion or interpretation of the scriptures, but its method for explaining its concepts is unique. Upanishad means pupils sit near the teacher to learn from him about the secret doctrine.
