But actually spiritual life is defined in the Gita, Krishna is impelling Arjuna, not to be lazy, but give all of his energy to fight for the sake of Krishna. And this is a real saintly person. He is willing to give all of his life's energies, exhaust everything he has, for the betterment of mankind in the service of God. That is a saint. Not someone who lays, and sleeps and eats some chapattis.
So we have to be patient, but at the same time we have to work very hard with great enthusiasm in the service of the Lord. And if we are very enthusiastic and patience, which is based on faith in the word of God, faith in the mercy of God then the combination of those two is surrender.
