" Changes can be made at the time of planning (charging of new karma), however once those plans [discharging of karma] start taking effect, they cannot be changed, because the world itself has attained the gross state from a subtle one. Meaning it has come into the ‘second stage’. It is not in the ‘first stage’. Changes can be made in the ‘first stage’. "

― Dada Bhagwan , The Science of Karma
