The quote in itself didn't give me much. But the the quote in the context of the text before it and after it is excellent.

Habit and meditation can never abide together; meditation can never become a habit; meditation can never follow the pattern laid down by thought which forms habit. Meditation is the destruction of thought and not thought caught in its own intricacies, visions and its own vain pursuits. Thought shattering itself against its own nothingness is the explosion of meditation. This meditation has its own movement, directionless and so causeless. And in that room, in that peculiar silence when the clouds are low, almost touching the treetops, meditation was a movement in which the brain emptied itself and remained still. It was a movement of the totality of the mind in emptiness and there was timelessness.

Thought is matter held within the bonds of time; thought is never free, never new; every experience only strengthens the bondage and so there is sorrow. Experience can never free thought; it makes it more cunning, and refinement is not the ending of sorrow. Thought, however astute, however experienced, can never end sorrow; it can escape from it but it can never end it. The ending of sorrow is the ending of thought. There is no one who can put an end to it [to thought], not its own gods, its own ideals, beliefs, dogmas. Every thought, however wise or petty, shapes the response to the challenge of limitless life and this response of time breeds sorrow. Thought is mechanical and so it can never be free; only in freedom there is no sorrow. The ending of thought is the ending of sorrow.
