Acharya Prashant explains that human dissatisfaction with the past is fundamentally linked to expectations from the future. When we regret the past, we are essentially trying to prepare for a future where those regrets are rectified. However, true peace is found only when one reaches the 'end,' where there is no longer a desire for the future. When the hope for the future vanishes, the resentment toward the past also disappears. He illustrates this with a story of a disciple who, believing he was about to die, immediately abandoned all his grudges and ambitions, realizing their triviality. This state of 'dying before death' is essential to stop the cycle of being crushed between past regrets and future anxieties.
