Krishna assures Arjuna that no attempt to improve his spiritual condition could possibly be a wasted effort. Even looking ahead to the next life, he has nothing to lose and everything to gain. He will be reborn in a household suitable for taking up his quest where he left off. In his next life, he will feel drawn to the spiritual goal once again, and he will have a head start. The general Hindu belief is that Self-realization requires many, many lives of spiritual discipline.
