Isn't it a contradiction that surrender can also involve an act of will?
Depends on the angle of vision. To submit, to surrender self to Self takes the greatest act of will because it stems from an active consciousness, not our usual reflexive or knee-jerk state of being.
And what is surrendered?
Yourself as you know or think yourself to be.
How to go about such an undertaking?
Bib by bit, certainly not a one time deal.
Through what means?
Through relinquishing false agency of action for the real thing; through efforts of letting go, turning over or funneling whatever we experience to a new center of gravity within ourselves, efforts inspired by and eventually fully stemming from that new center itself as ego-mind gets more and more out of the way.
What 's this new center of being?
Whatever we recognize or intuit or even imagine it to be.
Some call it God, some Self, some the Beloved, some the Master within, with or without form. Whatever the name or image, it acts as a magnet drawing us toward our Real Self until we see or become that.
Wait. You said 'imagine.' Isn't imagination something to get away from?
Yes and no. Why not put what you've already got to a creative and liberating use?
What makes it liberating if its the stuff of illusion?
The difference is in intention, intent, motive that comes from a different place. When that is in the driver's seat it uses imagination as a vehicle, puts its power to a new use.
