When one’s a pure devotee who is surrendered to Kṛṣṇa, then Krsna directly controls everything personally with that devotee. If one is not cent percent pure , upto whatever extent he’s not pure and still has different desires , different attachments, different material conditionings, he is subject to the laws of karma , and he has to suffer a certain degree of reaction. Krsna reduces that suffering( makes it a token), he may organise what comes before or after , but the suffering that one endures is really due to his own previous karma , however it reduced might be . So it has the sanction of Kṛṣṇa. Nothing happens without the sanction of Kṛṣṇa.
