As Kṛṣṇa is aja, we are also aja. That we do not know. This is ignorance. This is ignorance.
They are making scientific researches, but they do not know that every living entity is spirit soul. He has no birth. He has no death. He's eternal. Nityaḥ śāśvato 'yam, everlasting; purāṇaḥ, although oldest, na hanyate. The conclusion: na hanyate hanyamāne śarīre (BG 2.20). So after the annihilation of this body the soul does not die. He accepts another body. This is our disease. This is called bhava-roga. Bhava-roga means material disease.
