ṚBHU I. An ancient sage. He was the son of Brahmā. He was an extraordinary scholar who became the preceptor of Nidāgha who was the son of Pulastya and the grandson of Brahmā. Ṛbhu conveyed all knowledge to Nidāgha. But he saw that although he taught Nidāgha all branches of knowledge, the latter did not take any interest in “Advaita”. So he left him in disappointment but later got him interested in Advaita. (Viṣṇu Purāṇa, Aṃśa 2. Chapters 15-16).
