Q: Why do the lower forces attack the Yogi?
In order to bring him down to the lower level, so as to prevent him from ascending to the higher levels of consciousness and organising anything there. When I go up in consciousness and try to organise something above, these forces come and attack me and I have to come down and meet them. There is some kind of organisation of the higher Power here in the lower nature with which I have to meet them. For instance, it is possible to prevent people from getting ill, and this organisation is workable in practice and sufficient for us to go on with. But it is not what has got to be done, it is not the highest nor the perfect movement.
It is well known that once you come down in consciousness you find it difficult to go up again. There are two ways of meeting these attacks of the lower forces: (1) either you have to remain perfectly calm and allow the higher Power to protect you if it likes, or, (2) you have to come down and fight them with your forces.
