Why does Vajrasattva take so long to purify present-life karma but is quick to purify past-life karma?
Just the title basically, we've killed millions of people in our past lives through samsara and Vajrasattva purifies that quickly. But Bari Lotsawa killed a sorcerer and now he has to do Vajrasattva for a year which is probably 3x - 5x the amount of Vajrasattva ngondro for one murder. Karma that is immediately addressed should be easier to purify too, it should be quicker not longer (but is longer in practice).
Anyone know what causes this discrepancy?
