Mystery of Bhagvad Gita

Just like you'll find in the Bhagavad Gita that Krisna requesting Arjuna to become a yogi, but He never asked him to cease from the fight. How one can become a yogi, at the same time remain a fighter? That, a practical ex-ample you see. Krisna is asking Arjuna, tasmaad yogi bhavaarjuna. "My dear Arjuna, therefore you become a yogi." But at the same time, He's asking to fight. Now, we know the yogi sits down at a place and meditates and concentrates his mind and controls his senses. How is that he is fighting, and at the same time a yogi? Huh?

This is the mystery of Bhagavad Gita. You can remain a fighting man, at the same time the highest yogi, highest sannyasi. How? In Krisna consciousness. You have to fight for Krisna. That's all. That is the secret. That is the secret.
