I must keep always in mind that you are assumed to know nothing whatever about Yoga and Magick, or anything else beyond what the average educated person may be assumed to have been taught.
What is the problem? There are two.
β: To train the mind to move with the maximum speed and energy, with the utmost possible accuracy in the chosen direction, and with the minimum of disturbance or friction. That is Magick.
α: To stop the mind altogether. That is Yoga.
The rules, strangely enough, are identical in both cases; at least, until your “Magick” is perfect; Yoga merely goes on a step further. In Beta you have reduced all movements from many to One; in Alpha you reduce that One to Zero.
