Actually, this Kṛṣṇa consciousness movement, practically showing how to cultivate the devotional life, taj-joṣaṇāt. And if we do so, then āśu. Āśu means very soon, without delay, even in this life. Even in this life, not that we have to wait for another life. If we practice devotional service in this life, even for few days, still, it will be a permanent asset.
-Lecture on SB 3.25.25 -- Bombay, November 25, 1974

प्रयाणकाले मनसाचलेन
भक्त्य‍ा युक्तो योगबलेन चैव ।
भ्रुवोर्मध्ये प्राणमावेश्य सम्य-
क्स तं परं पुरुषमुपैति दिव्यम् ॥ १० ॥
One who, at the time of death, fixes his life air between the eyebrows and, by the strength of yoga, with an undeviating mind, engages himself in remembering the Supreme Lord in full devotion, will certainly attain to the Supreme Personality of Godhead.
-Bhagavad-Gita Chapter 8 Verse 10
