At the time of death, the mental condition which you have created, that will carry you to the next body. Therefore don't create your mind doggish. Make it Kṛṣṇa conscious. And that is very nice. Then at the time of death you remember Kṛṣṇa, and you will be transferred to the Kṛṣṇaloka. That is described: etāvān sāṅkhya-yogābhyām. Therefore it is advised, "Whatever you may be, it doesn't matter. Practice Kṛṣṇa consciousness. That will save you." Otherwise . . . janma-lābhaḥ paraḥ puṁān. Janma-lābhaḥ paraḥ puṁsām ante (SB 2.1.6).
This janma-lābhaḥ paraḥ. Janma-lābhaḥ. Janma-lābhaḥ means getting a type of birth. So there are different types of birth. The so-called scientists, physicists, they do not know why there are so many varieties of life. Why not only human being? Why there is cat, there is dog, there is rat, there is fly and there is serpent, there is tree, there is creeper, there is fish, there is so many, 8,400,000 species of life? So they are also taking their birth by father and mother. The insect or the cats and dog or human being, the process of birth is the same, father and mother, anywhere you go. Therefore one Vaiṣṇava poet has sung:
- janame janame sabe pitā-mātā pāya
- kṛṣṇa guru nahi mile bhaja hari ei
- (Prema-vivarta)
Everywhere, either you take birth as man or cat or dog or insect, there is father, mother. Father, mother you will get in any type of birth, but not guru and Kṛṣṇa.
