My preception:
Sri Krsna is perfect in every way. Subsequently his actions are perfect in everyway.
Perhaps, our sufferings are the results of our Karma.
Perhaps, the misery, caused by suffering, is an indication of our ignorance.
Perhaps, in suffering or in celebrations one must perform his precribed duties without attachemet and without expectations.
Perhaps, jubilations and sufferings are mere maya. Jubilations and sufferings loses it's meaning as one advances on spiritual path.
Even the Demi Gods and the Rishi's fail to understand Sri Krsna completely. Then, what to speak of mortals like me.
In hard times, I normally try to perform my duties and leave the rest to the One Who Knows Everything.
