Vāsanā — Residual Impressions from Past Karma
Vāsanā (Sanskrit: vas = to dwell/remain; 'that which remains/lingers') refers to the subtle psychological impressions — the tendencies, cravings, and habits — that past actions (karma), experiences, and desires leave embedded in the sūkṣma śarīra (subtle body). These residual impressions shape the soul's future desires, decisions, and rebirths.
How Vāsanā Works: Every action, thought, and experience leaves a trace in the subtle body. Repeated actions deepen these traces into habits and cravings. 'As water flowing repeatedly over stone carves a channel, repeated desires carve channels (vāsanās) in the subtle body.' These channels then pull the soul toward repeating the same actions in the future.
Three Types of Vāsanā:
- Karma vāsanā — traces from actions
- Śāstra vāsanā — traces from scriptural study and spiritual practice (beneficial)
- Viṣaya vāsanā — traces from sense experiences (generally binding)
Removing Vāsanā: In Mumukshuppadi, Pillai Lokāchārya teaches that avidyā (ignorance), karma, and vāsanā together form the triple chain of saṃsāra. Bhagavān's grace, working through prapatti, burns away even the deepest vāsanās. 'The fire of the Lord's grace can destroy all vāsanās instantaneously — what austerity cannot accomplish in eons, His grace accomplishes in a moment.'
