Why does Bhagavan Krishna give sufferings to even those who love him?
Sri Sri Muralidhara Swamiji:
The hell is full of sorrows and the heaven is full of joy. But for anyone and everyone on earth, it is a mixture of both joy and sorrow.
To forget this mixed results of joy and sorrows, we should be totally immersed in Bhagavan Krishna's eternal bliss.
It is only in order to get his most loved ones into that state, Krishna, an ocean of compassion, gives sufferings.
Sri Sri Muralidhara Swamiji
"Joy and sorrow are the only two known states of mind as far as humankind is concerned.
Divinity is to get past this dual state and be in the state of constant bliss"
