when the recruit asks 'What made that 'ole?' he has got to say, unsmiling, 
'Mice.' 
     Pluto is the utmost sentinel of all; of him it is not wise to speak. . . . 
Having now given vent to this sibylline, obscure and sinister utterance, it 
may well be asked by the greatly daring: Why is it not wise to speak of 
Pluto? The answer is profound. It is because nothing at all is known about 
him. 
     Anyhow it hardly matters; we have surely had enough of Niyama for 
one evening! 
     19. It is now proper to sum up briefly what we have learnt about 
Yama and Niyama. They are in a sense the moral, logical preliminaries of 
the technique of Yoga proper. They are the strategical as opposed to the 
tactical dispositions which must be made by the aspirant before he 
attempts anything more serious than the five finger exercises, as we may 
call them—the recruit's drill of postures, breathing exercises and 
concentration which the shallow confidently suppose to constitute this 
great science and art. 
     We have seen that it is presumptuous and impractical to lay down 
definite rules as to what we are to do. What does concern us is so to 
arrange matters that we are free to do anything that may become 
necessary or expedient, allowing for that development of supernormal 
powers which enables us to carry out our plans as they form in the 
mutable bioscope of events. 
     If anyone comes to me for a rough and ready practical plan I say: 
Well, if you must stay in England, you may be able to bring it off with a 
bit of luck in an isolated cottage, remote from roads, if you have the 
services of an attendant already well trained to deal with the emergencies 
that are likely to arise. A good disciplinarian might carry on fairly well, at 
a pinch, in a suite in Claridge's. 
     But against this it may be urged that one has to reckon with unseen 
forces. The most impossible things begin to happen when once you get 
going. It is not really satisfactory to start serious Yoga unless you are in a 
country where the climate is reliable, and where the air is not polluted by 
the stench of civilisation. It is extremely important, above all things 
important, unless one is an exceedingly rich man, to find a country where 
the inhabitants understand the Yogin mode of life, where they are 
sympathetic with its practices, treat the aspirant with respect, and 
unobtrusively assist and protect him. In such circumstances, the exigency 
of Yama and Niyama is not so serious a stress. 
     There is, too, something beyond all these practical details which it is 
hard to emphasise without making just those mysterious assumptions 
which we have from the first resolved to avoid. All I can say is that I am 
very sorry, but this particular fact is going to hit you in the face before 
you have started very long, and I do not see why we should bother about 
the mysterious assumptions underlying the acceptance of the fact any 
more than in the case of what is after all equally mysterious and 
unfathomable: any object of any of the senses. The fact is this; that one
