The Evolution of the Tattvas 65 



ual, mental, and physical which I assume all my 

 readers are seeking, the practice must be regular 

 and at the regular periods as nearly as possible 

 the same daily. Never let any of the exercises be- 

 come automatic. Hold the mind to the center. 



I have tried to make it very clear that the pur- 

 pose of the exercises in alternate breathing is to 

 restore the balance of the Tattvas and the alter- 

 nating currents of Prdna (positive and negative), 

 the inequality of which is the primary source of all 

 disease. Habitual breathing should be as full, 

 deep, and regular as conscious direction from time 

 to time can make it. Habit is everything in this, 

 and in forming good habits Nature comes to our 

 aid with joyful alacrity. I have failed utterly in 

 my purpose if I have not convinced you that phy- 

 sical, mental, and spiritual harmony are promoted 

 by habits of rhythmic breathing in the purest air 

 obtainable. It need not be cold air to be pure, 

 but it must be fresh, unbreathed air. 



Continued practice of the exercises will convince 

 you that you are treading the long hidden, closely 

 guarded path leading to Nature's treasury of se- 

 crets. If your interests and pursuits are scientific, 

 before your clearing vision wall after wall, hith- 

 erto baffling, will fall, disclosing long vistas 

 cleared and ready for your seeing eyes with as- 

 sured foundations, basic laws, inviting your fas- 

 cinating experiments into the myriad permutations
