Self == Selflessness

From Liber B Vel Magi:

"16. Let the Magus then contemplate each in turn, raising {8} it to the ultimate power of Infinity. Wherein Sorrow is Joy, and Change is Stability, and Selflessness is Self. For the interplay of the parts hath no action upon the whole. And this contemplation shall be performed not by simple meditation --- how much less then by reason! but by the method which shall have been given unto Him in His initiation to the Grade."

According to the Kybalion - all opposites ultimatley resolve - it is called the Law of Polarity:
"Everything is dual; everything has poles; everything has its pair of opposites; like and unlike are the same; opposites are identical in nature, but different in degree; extremes meet; all truths are but half-truths; all paradoxes may be reconciled."

So how is the Selflessness Self?

Mahayana Buddhism teaches at times, that "Selfishness" creates "Selflessness" - that Selfishness and Self meet. The teaching is sublime - but comes to a concept that if we want the best things for ourselves, we must give the best things to others. To gain peace, we must give peace. To have wealth, we must give wealth. To procure love, we must love others. Some might find this not very altruistic - but does it matter? For behaving this way, one melts the self into selflessness.

With this frame of reference, perhaps a key can be constructed to unlock Liber NV:
"9. Let the Aspirant beware of the slightest exercise of his will against another being. Thus, lying is a better posture than sitting or standing, as it opposes less resistance to gravitation. Yet his first duty is to the force nearest and most potent; e.g. he may rise to greet a friend.This is the third practice of Ethics (ccxx. I. 41).
10. Let the Aspirant exercise his will without the least consideration for any other being. This direction cannot be understood, much less accomplished, until the previous practice has been perfected.This is the fourth practice of Ethics (ccxx. I. 42, 43, 44). "

It seems to me at first glance, to opposites here... to beware of the slightest exercise of one's will against another... Then in the next verse, to exercise one's will without the least consideration for any other being. The clue here is the end of verse 10, that this can't be understood or acomplished until the previous practice has been perfected.

If I were to perfect being aware of the slightest exercise of my will against another - I would perfect my behavior to such a degree to work to my best return. Selfless, as it were. Once perfected, my true will could be established without the consideration of any other being. But if I were to attempt to exercise my will first (without consideration of any other being), I would become unbalanced - egotistic, hostile perhaps. But with the first part, my will would guide my love.
