Accidentally (Books)
Bhagavad-gita As It Is
BG Chapters 7 - 12
BG 8.23, Purport:
If the yogī is perfect he can select the time and situation for leaving this material world. But if he is not so expert his success depends on his accidentally passing away at a certain suitable time. The suitable times at which one passes away and does not come back are explained by the Lord in the next verse. According to Ācārya Baladeva Vidyābhūṣaṇa, the Sanskrit word kāla used herein refers to the presiding deity of time.
