Śrīmad-Bhāgavatam · Text 12.6.25
Who is speaking and story frame
जीवितं मरणं जन्तोर्गति: स्वेनैव कर्मणा ।
राजंस्ततोऽन्यो नास्त्यस्य प्रदाता सुखदु:खयो: ॥ २५ ॥
jīvitaṁ maraṇaṁ jantor
gatiḥ svenaiva karmaṇā
rājaṁs tato ’nyo nāsty asya
pradātā sukha-duḥkhayoḥ
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.
