Bhagavad Gita · Chapter 12: The Path of Devotion

Bhagavad Gita 12.10

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

If you are not capable even of practice, then devote yourself to working for me. By doing actions for my sake, too, you will attain perfection.

Modern context

If even practice is too hard, then simply do your work for the divine. This is the next step down, and it is open to almost everyone. Not everyone can meditate. Not everyone has time for daily spiritual practice. But anyone can cook, clean, teach, build or care for others with the thought 'this is for You'. And Krishna says that this too leads to perfection.
