The Ashvattha — the sacred peepal tree — holds a revered place in Hindu tradition. In Chapter 15, Krishna will use it as a metaphor for the entire cosmos. Here, He names it as the foremost among trees. A tree that gives shade to travellers, that is worshipped at village crossroads, that stands for generations — the divine lives in it.
Narada — the divine sage who travels through all three worlds chanting Narayana-Narayana — is the foremost symbol of bhakti. Kapila Muni is the founder of the Sankhya school of philosophy. Knowledge and devotion both find their place in the vibhuti list. Neither is excluded.
