Only devotional service to Krishna survives death; all else perishes with the material body.Listen — Srila Prabhupada Uvaca
The Nectar of Devotion — December 27, 1972, Bombay 721227ND-BOMBAY [29:18 Minutes] NOD_721227ND-BOMBAY Pradyumna: [reading:] "...immediately terminates along with his body as soon as his life is over. Death is therefore taken as the representative of God for the atheistic class of men. The devotee realizes the presence of God by devotional service, whereas the atheist realizes the presence of God in the shape of death. At death everything is finished, and one has to begin a new chapter of life in a new situation, perhaps higher or lower than the last one.
In any..." Prabhupāda: Yes. Bhagavad-gītā, it is said, Kṛṣṇa says: mṛtyuḥ sarva-haraś ca aham [Bg. 10.34]. At the... By death, everything is taken away by Kṛṣṇa.
So the modern civilization, they do not believe in the next birth. That is the basic mistake of the present civilization, that we get information that tathā dehāntaraṁ prāptir dhīras tatra na muhyati [Bg. 2.13]. Dehāntaram. Just like we are transmigrating, even in this span of life, from childhood to boyhood, from boyhood to youthhood, from youthhood to old age body.
Therefore it is naturally to conclude that after this old body's finished, then we get another body, transmigration of the soul. But there is no education, no enlightenment about this transmigration of the soul. But we can, if we think, ponder very deeply on this matter, how transmigration of the soul is taking place. And it is authorized, authorized statement of Bhagavad-gītā: tathā dehāntaraṁ prāptir. dehino 'smin yathā dehe kaumāraṁ yauvanaṁ jarā tathā dehāntaraṁ prāptir dhīras tatra na muhyati [Bg. 2.13] So this is the defect.
The atheist class of men, they also see God. One..., everyone can see God, provided he has got eyes to see. Actually, premāñjana-cchurita-bhakti-vilocanena santaḥ sadaiva hṛdayeṣu vilokayanti [Bs. 5.38]. Those who are yogīs, bhakta-yogīs, because they are in love with God, Kṛṣṇa, they are seeing every moment within their heart the Supreme Personality of Godhead.
Anyone you love, you see always within your heart. Similarly, if you have love for God, Kṛṣṇa, then you can see Kṛṣṇa always. That is called yoga system. Dhyānāvasthita-tad-gatena manasā paśyanti yaṁ yoginaḥ [SB 12.13.1]. Yoginaḥ, those who are yogīs, under meditation they see the Supreme Personality of Godhead within the heart.
Dhyānāvasthita-tad-gatena manasā paśyanti yaṁ yoginaḥ. So there are many evidences in the śāstras. Yoga means to see the Supreme Lord within the heart. Īśvaraḥ sarva-bhūtānāṁ hṛd-deśe arjuna tiṣṭhati [Bg. 18.61]. Īśvara, the Supreme Lord, is situated in everyone's heart. One has to see. One has to develop that visionary power, how to see God within the heart.
