Bhagavad Gita 12.10

अभ्यासेऽप्यसमर्थोऽसि मत्कर्मपरमो भव।मदर्थमपि कर्माणि कुर्वन् सिद्धिमवाप्स्यसि॥

abhyāse'pyasamartho'si matkarmaparamo bhava |madarthamapi karmāṇi kurvan siddhimavāpsyasi ||

If you are unable to practice even this Abhyasa Yoga, be intent on doing actions for My sake; even by doing actions for My sake, you will attain perfection.

And if you are not strong enough to practice concentration, then devote yourself to My service, do all your acts for My sake, and you will still attain the goal.

Our plain-language meaning of this verse is waiting for scholar review.
