Bhagavad Gita · Chapter 18: Freedom through Renunciation

Bhagavad Gita 18.60

svabhāvajena kaunteya nibaddhaḥ svena karmaṇā | kartuṃ necchasi yanmohātkariṣyasyavaśo'pi tat ||

Bound by your own action, which is born of your nature, Arjuna, you will do helplessly the very thing that, in your delusion, you do not want to do.

Modern context

What you do not want to do out of delusion, you will do anyway, compelled by your own nature. This is a sobering thought. Sometimes we resist what we must eventually do, and the resistance only makes it harder. It is better to understand and accept one's duty clearly than to be dragged into it unwillingly.
