How to use the Master-Key 47 



It is by controlling these bodies of ours first, 

 with all their passions and emotions none of 

 them designed for our undoing but as schools of 

 strength that we build the ladders which carry 

 us to unknown, almost unbelievable heights of in- 

 tellectual and spiritual power; heights where we 

 know that all lasting, enduring power is indis- 

 solubly united with, because proceeding from, the 

 spiritual force; and is fed by rhythmic currents 

 of Tattvic vibrations of so high and subtle a char- 

 acter that they are unaffected by the disturbances 

 on the grosser planes of being. Only spiritually 

 can we know them; and in rare, exalted moments 

 they give us a perception of the " Harmony of 

 the Spheres." The source of strength thus 

 opened to one is inexhaustible. Practice will give 

 every human being access to it, for the reservoir 

 is within every soul. 



The effective use of the master-key is by means 

 of concentration. Only thus can we gain so firm 

 a hold upon the key that we can unlock and open 

 the magic realm of power to which it gives access. 

 The practice of the exercises for Prdndyama puri- 

 fies the body through the impetus it gives to the 

 expulsion of all wastes, and it greatly increases 

 the flow of the most favorable Tattvas, which, 

 speeding rhythmically over the nerves, clear the 

 channels of all jarring and jangling vibrations, 

 those irregular and abnormal atomic vibrations
