Yoga Sūtra Chapter Two verse 9
स्वरस्वाहि विदुषोऽपि समारूढोऽभिनिवेशः ॥९॥
sva-rasa-vāhī viduṣaḥ api samā-ruḍhaḥ abhiniveśaḥ ||9||
The will to stay alive is a continuous self-disposition;
constantly springing up, even in the wise person.
Commentaries and ReflectionsT Krishnamacharya:
Abhiniveśā is the extra-ordinairy instinctive urge to survive at any cost.
No one is spared.
In a way it is a dislike about one’s death.
There are essentially three causes for fear….
desire, disease and death.
