Srimad-Bhagavatam: Canto 12 - Chapter 1 - Verse 25

Sanskrit:

जीवितं मरणं जन्तोर्गति: स्वेनैव कर्मणा ।राजंस्ततोऽन्यो नास्त्यस्य प्रदाता सुखदु:खयो: ॥ २५ ॥

ITRANS:

jīvitaṁ maraṇaṁ jantorgatiḥ svenaiva karmaṇārājaṁs tato ’nyo nāsty asyapradātā sukha-duḥkhayoḥ

Translation:

The life and death of an embodied soul and his destination in the next life are all caused by himself through his own activity. Therefore, O King, no other agent is actually responsible for creating one’s happiness and distress.

Purport:

Although King Parīkṣit apparently died by the bite of Takṣaka, it was Lord Kṛṣṇa Himself who brought the King back to the kingdom of God. Bṛhaspati wanted young King Janamejaya to see things from the spiritual point of view.
