Bhagavad Gita 18.9 · Krishna
The clear way to let go
कार्यमित्येव यत्कर्म नियतं क्रियतेऽर्जुन।
सङ्गं त्यक्त्वा फलं चैव स त्यागः सात्त्विको मतः॥
kāryamityeva yatkarma niyataṃ kriyate’arjunasaṅgaṃ tyaktvā phalaṃ caiva sa tyāgaḥ sāttviko mataḥ
When rightful work is done because it should be done, Arjuna, without clinging or craving its fruit, that letting go is clear.
What it means
Krishna describes sattvic letting go, the clear kind. You keep doing your duty, simply because it's yours to do. But you let go of clinging, and of craving for the fruit. The work stays. The grip goes. This is the tyaga Krishna has been teaching all along.
The story
This is the answer to Arjuna's crisis. Don't drop the bow. Drop the anxious grip. Do what's yours, and leave the outcome open.
In your life
Imagine a carer who looks after a sick parent every day, not for thanks, simply because it's right, and with love. Do one duty today with that clear heart.
Keep the work. Release the grip.
