Chapter 2 · The Yoga of Knowledge · Krishna said
Bhagavad Gita 2.50 — Yoga is skill in action
बुद्धियुक्तो जहातीह उभे सुकृतदुष्कृते। तस्माद्योगाय युज्यस्व योगः कर्मसु कौशलम् ॥
buddhiyukto jahātīha ubhe sukṛtaduṣkṛte | tasmādyogāya yujyasva yogaḥ karmasu kauśalam ||
Meaning
A person with this wisdom leaves behind both good and bad deeds even here. So devote yourself to yoga; yoga is skill in action.
In today's life
Whatever your job, doing it carefully and honestly, without selfish worry, is itself a spiritual practice.
