QUOTE : Krishna, what happens to he who strays from the path of insight? Does he lose out on both: happiness promised by wisdom and pleasures promised by indulgence? Does he perish like a torn cloud?—Bhagavad Gita: Chapter 6, verses 37 and 38 (paraphrased). Krishna replies that nothing is wasted or destroyed in the cosmos. All efforts are recorded and they impact future lives. Knowledge acquired in the past plays a role in the wisdom of future lives. Those unsuccessful in realization in this life will be reborn. Their efforts will not go in waste. They will ensure they are born in a wise family, where they can strive again. They will be driven to wisdom on account of memories and impressions of previous lives. By striving through many lives, they untangle themselves to unite with divinity.—Bhagavad Gita: Chapter 6, verses 41 to 45 (paraphrased).
