Immortality is only attained through sacrifice. When we sacrifice worldly life for God, the effects of Karma disappear.
We just perform the actions that destiny presents before us as duty. This delusion inhibits us from carrying out our assigned tasks, and can take many forms. We may feel that others’ Dharma is easier, but in reality it is not so. Our Swadharma alone is best suited to us. Our present situation is solely to do with our past Karmas and as such is the best path for us. We can grow spiritually only by discharging them properly.
