FAQs
It teaches that Keśava-worship becomes “uttama” (supreme) when grounded in single-pointed devotion to Nārāyaṇa and supported by inner discipline—especially restraint of speech and mindful conduct even in eating.
Bhakti here is not only ritual offering but a transformed orientation—“nārāyaṇa-para”—expressed through self-control (vāk-yama) and regulated living, showing that devotion is both love and disciplined practice.
The verse emphasizes ritual discipline (niyama) and purity of conduct during worship—closely aligned with Kalpa (rules of ritual procedure) and Śikṣā-like attention to controlled speech (vāk-saṃyama) as part of sacred practice.
