Adhyāya 51: Kṛṣṇa’s Leave-Taking and Departure for Dvārakā (द्वारकागमनानुमति)
प्रसादे चैव सत्त्वस्य प्रसादं समवाप्नुयात् लक्षणं हि प्रसादस्य यथा स्यात् स्वप्नदर्शनम्,सम्पूर्ण अन्त:करणके स्वच्छ हो जानेपर साधकको शुद्ध प्रसन्नता प्राप्त होती है। जैसे स्वप्नसे जगे हुए मनुष्यके लिये स्वप्न शान्त हो जाता है, उसी प्रकार चित्तशुद्धिका लक्षण है
prasāde caiva sattvasya prasādaṁ samavāpnuyāt | lakṣaṇaṁ hi prasādasya yathā syāt svapnadarśanam ||
Vāyu said: “When the inner being (sattva) becomes serene, one attains serenity itself. The mark of such serenity is this: just as, for a person who has awakened, the dream-vision becomes quiet and loses its hold, so too the sign of purification is the mind’s clear, undisturbed gladness.”
वायुदेव उवाच
True purification is recognized by prasāda—lucid, steady serenity. When sattva becomes clear, mental disturbances subside naturally, like a dream losing reality upon waking.
Vāyudeva instructs the listener on the experiential sign of inner purification: the mind becomes transparently calm, and illusory or agitating impressions fade the way dream-images fade after awakening.
