Om Swami
What makes an action truly right according to the Gita?
Join truth and goodness to good action
Bhagwan tells Arjuna that the word "sat" should be joined to every good action. Truthfulness and sattvikta (goodness) belong in it, and it should be done for God.
In every good action there should be truthfulness and purity, and what is done should be done for God.
