Renunciation does not simply mean to give up that which one desires. It also means to renounce the possibility for evermore of being tempted by life in the three worlds of matter. It means that should we even consider the possibility of acting harmfully against another, in thought, speech or deed, then we have strayed from the Path of the renunciate. If we truly wish to set out feet upon this pathway then we needs must begin today by striving to think, speak and act in a way that is harmless. To achieve such a momentous goal one needs to be in a constant state of vigilance, guarding every thought.
Actions stem from the world of thought.
If we are able to purify our thoughts, then soon harmlessness must follow. This is the Law. So how do we go about attaining this goal and thus moving closer to enlightenment. By following the precepts as given out by the Lord Gautama Buddha. Right Thought, Right Speech, Right Mode of Living, and Right Memory.
