"Going with the flow" is for some people an excuse for not taking action and it refers usually to one's life situation.
Eckhart TolleComplete surrender usually happens through living. Your very life is the ground where that happens. There may be a partial surrender and then there may be an opening, and then you may engage in spiritual practice.
Eckhart TolleBy learning to accept the small things immediately as they happen, you can be free of having to react to things at all. You still can respond when action is needed, but you can be free, internally, of events.
Eckhart TollePersonally, I don't teach practices as such. The power of the teaching is sufficient without needing to go for any practice.
