1. A devotee acts according to Krsna’s desire

    If Krsna wants, the devotee can do anything which is ordinarily undesirable;
    and if Krsna does not want, he shall not do that which he would have ordinarily done for his own satisfaction.

    From Bg 2.64 ppt.

    As described in The Nectar of Devotion:

    Pradyumna's attachment for Krsna was always exhibited by his action. Whenever he was ordered by his father to execute something, he would immediately execute the order, taking the task as nectarean even though it may have been poison. Similarly, whenever he would find something to be disapproved of by his father, he would immediately reject it as poison, even though it may have been nectarean.
