I do not suppose they [the commentators] mean expressly intuition [by buddhi]; they regard buddhi as the means of knowledge, so they include all knowledge in it, and as the vijñānamaya koṣa is the Knowledge sheath, they think it must mean buddhi. Obviously it doesn’t. The description you have quoted1 evidently means something much higher than buddhi. It is the satyam ṛtaṃ bṛhat of the Upanishad – the truth-consciousness of the Veda.
