Abandon every attempt, just be; don't strive, don't struggle, let go every support, hold on to the blind sense of being, brushing off all else. This is enough. Nisargadatta Maharaj
You cannot control your way to freedom. You cannot concentrate your way to heaven. If you want to find it, see that the very idea of "someone who is in control" is a concept created by the mind, and lay it down. Don't touch it. If you touch it, it will bite you. Surrender is the ticket, and there is nowhere to get to.
