Vairagya

True vairāgya refers to an internal state of mind rather than to external lifestyle and can be practiced equally well by one engaged in family life and career as it can be by a renunciate.

Balance is maintained between the inner spiritual state and one's external life through the practice of seeing all limited entities as expressions of the one Cosmic Consciousness or Brahman.

[5] The concept of Vairāgya is found in the Yoga Sūtras of Patañjali, where it, along with practice (abhyāsa), is the key to restraint of the modifications of the mind (YS 1.12, "abhyāsa-vairāgyabhyāṁ tannirodhaḥ").

The term vairāgya appears three times in the Bhagavad Gita (6.35, 13.8, 18.52) where it is recommended as a key means for bringing control to the restless mind.

[9] Krishna tells Arjuna that acting with detachment means doing the right thing for its own sake, because it needs to be done, without worrying about success or failure.

Krishna says to Arjuna not to give up upon doing his best because its what destiny demands of him to perform his best with his role, his destiny is his continued good performance of his role, the detachment is in not being impassioned by the feelings associated in living with continued awareness of success and failure because both are irrelevant.
