A - Your Duty to Yourself: "Learn to understand clearly how best to manipulate the energies which you control to obtain the results most favorable to it from it?s relations with the part of the Universe which you do not yet control."
B - Your Duty to other Individual Men & Women: "...studying the methods which determine their failure or success, acquire for yourself the wit and skill required to cope with your own problems."
C - Your Duty to Mankind: "Governments too often exhibit the most deplorable stupidity...therefore incumbent on every man and woman to take the proper steps to cause the revision of all existing statutes on the basis on the Law of Thelema;" "...The ultimate aim is thus to reintegrate Conscience, on true scientific principles, as the warden of conduct..."
D - Your Duty to all other Beings & Things; "The inherent fitness of any thing for any proposed use should be the sole criterion;" "...violation of the Law of Thelema produces cumulative ills;" "The wise application based on... the Law of Thelema... is to work in conscious harmony with Evolution;" "...value is to be judged by their fertility as bearing witness to their harmony with the course of nature towards perfection." "Muscular power is based upon the rigidity of bones, and upon the refusal of joints to allow any movement in any but the appointed directions. The more solid the fulcrum, the more efficient the lever."
"We start to penetrate the stratosphere; and we have to modify our machines in all sorts of ways which were not altogether foreseen. I wish to thunder forth once more that no questions of right or wrong enter into our problems. But in the stratosphere it is 'right' for a man to be shut up in a pressure-resisting suit electrically heated, with an oxygen supply, whereas it would be 'wrong' for him to wear it if he were running the three miles in the summer sports in the Tanezrouft. This is the pit into which all the great religious teachers have hitherto fallen, and I am sure you are all looking hungrily at me in the hope of seeing me do likewise. But no! There is one principle which carries us through all conflicts concerning conduct, because it is perfectly rigid and perfectly elastic: -- 'Do what thou wilt shall be the whole of the law'."
Indeed, this seems to be an important aim for a Thelemite to keep in mind; the reaching of that organic coherence within any setting where s/he has an impact upon reality – to work in conscious harmony with Evolution.
