Srimad-Bhagavatam

SB Canto 10.1 to 10.13

As for the python, however, by the association of Kṛṣṇa and His devotees, Aghāsura also achieved the same facility of eternal life. Therefore, as indicated here by the word ātmāhi-mokṣaṇam, if the python Aghāsura could receive eternal association with the Supreme Personality of Godhead, what is to be said of those who are already associates of the Lord?.

SB 10.12.37, Translation and Purport

This incident of Kṛṣṇa's saving Himself and His associates from death and of giving deliverance to Aghāsura, who had assumed the form of a python, took place when Kṛṣṇa was five years old. It was disclosed in Vrajabhūmi after one year, as if it had taken place on that very day.

The word mokṣaṇam means "liberation." For the associates of Kṛṣṇa and for Kṛṣṇa Himself, there is no question about liberation; they are already liberated, being in the spiritual world. In the material world there are birth, death, old age and disease, but in the spiritual world there are no such things because everything is eternal. As for the python, however, by the association of Kṛṣṇa and His devotees, Aghāsura also achieved the same facility of eternal life. Therefore, as indicated here by the word ātmāhi-mokṣaṇam, if the python Aghāsura could receive eternal association with the Supreme Personality of Godhead, what is to be said of those who are already associates of the Lord? Sākaṁ vijahruḥ kṛta-puṇya-puñjāḥ (SB 10.12.11). Here is proof that God is good for everyone. Even when He kills someone, the one who is killed attains liberation. What then is to be said of those who are already in the association of the Lord?
