Śrīmad-Bhāgavatam · Text 7.15.34
Who is speaking and story frame
एवमभ्यस्यतश्चित्तं कालेनाल्पीयसा यते: ।
अनिशं तस्य निर्वाणं यात्यनिन्धनवह्निवत् ॥ ३४ ॥
evam abhyasyataś cittaṁ
kālenālpīyasā yateḥ
aniśaṁ tasya nirvāṇaṁ
yāty anindhana-vahnivat
When the yogī regularly practices in this way, in a short time his heart becomes fixed and free from disturbance, like a fire without flames or smoke.
