The process, the work of becoming alive, asks for much letting go and for much learning to stay.

In Buddhism, a Bhodisattva (one who vows to achieve enlightment for the benefit of others, through all lifetimes), trains in both letting go of many things so as to be available to life and learning to stay. 

Learning to stay means learning to not run away from difficult situations, to not numb out in our life. It begins with compassion for ourselves, to beginning to see how our life actually works, all the crazy little ways we operate to not be present to our actual life

and then slowly extends to others. It is a life of always learning and never giving up, never giving up.

It happens over unending lifetimes.
