The Kingdom of God is Within You by Leo Tolstoy Chapter 12 Page 189

Devoting his life to works of the flesh, a man busies himself with actions depending on temporary causes outside himself. He himself does nothing really, he merely seems to be doing something. In reality all the acts which seem to be his are the work of a higher power, and he is not the creator of his own life, but the slave of it. Devoting his life to the recognition and fulfilment of the truth revealed to him, he identifies himself with the source of universal life and accomplishes acts not personal, and dependent on conditions of space and time, but acts unconditioned by previous causes, acts which constitute the causes of everything else, and have an infinite, unlimited significance.

“The kingdom of heaven suffereth violence, and the violent take it by force.” (Matt. xi. 12.)
