Therefore, it is of the utmost importance that we strive by every possible means to increase the quality and quantity of skillful actions and to make a corresponding paring down of our unskillful actions.

How is this to be accomplished? Meritorious and unmeritorious causes which result in pleasure and pain do not resemble external objects. For instance, in the human bodily system different parts such as lungs, heart and other organs can be replaced with new ones. But this is not so in the case of karmic actions, which are purely of the mind. The earning of fresh merits and the eradicating of bad causes are purely mental processes. They cannot be achieved with outside help of any kind. The only way to accomplish them is by controlling and disciplining the hitherto untamed mind. For this, we require a fuller comprehension of the element called mind.

Through the gates of the five sense organs a being sees, hears, smells, tastes and comes into contact with a host of external forms, objects and impressions. Let the form, sound, smell, taste, touch and mental events which are the relations of the six senses be shut off. When this is done the recollection of past events on which the mind tends to dwell will be completely discontinued and the flow of memory cut off. Similarly, plans for the future and contemplation of future action must not be allowed to arise. It is necessary to create a space in place of all such processes of thought if one is to empty the mind of all such processes of thought. Freed from all these processes there will remain a pure, clean, distinct and quiescent mind. Now let us examine what sort of characteristics constitute the mind when it has attained this stage. We surely do possess some thing called mind, but how are we to recognize its existence? The real and essential mind is what is to be found when the entire load of gross obstructions and aberrations (i.e. sense impressions, memories, etc.) has been cleared away. Discerning this aspect of real mind, we shall discover that, unlike external objects, its true nature is devoid of form or color; nor can we find my basis of truth for such false and deceptive notions as that mind originated from this or that, or that it will move from here to there, or that it is located in such-and-such a place.
