It is for the Guru to point out the method; he will show you the way to understanding and instruct you in your sadhana. It is for you to keep on practiCing it faithfully. But the fruit comes spontaneously in the form of Self-revelation.
The power to make you grasp the Ungraspable duly manifests itself through the Guru. Where the question "How am I to proceed?" arises, fulfillment has obviously not yet been reached.
Therefore, never relax your efforts until there is Enlightenment. Let no gaps interrupt your attempt, for a gap will produce an eddy, whereas your striving must be continuous like the flowing of oil, it must be sustained, constant, an unbroken stream.
