Meaning : Arjuna, there are many paths of sacrifice. Some give wealth, some follow strict disciplines, some meditate through yoga, and others seek Me through study and knowledge. Each is a valid offering, when done with sincerity and dedication. These acts purify the soul and guide the seeker closer to truth.
