The statement is false; the Upanisads are not a collection of the Vedas but are a separate set of philosophical texts that belong to the Vedic corpus and form the basis of Hindu philosophy, known as Vedanta.
Step-by-step explanation:
False, The Upanishads are not a collection of the Vedas.
The Upanishads are philosophical works that are considered to be a part of the Vedas.
