FAQs
It defines the true inner purification as ātmavedana—direct knowing/realization of the Ātman—implying that spiritual cleanliness is ultimately an inward awakening, not merely an external rite.

While this specific verse names Viṣṇu as the focus of yogic contemplation, its broader Purāṇic frame supports a synthesis where inner realization (Ātman-knowledge) is primary and devotional-yogic contemplation functions as a shared, non-sectarian means across Śaiva–Vaiṣṇava traditions.
