These visitations of a higher presence may deceive him into thinking that he has reached a higher degree than he really has. If so, he may expect their light and strength to abide permanently with him. In that case he may plunge into emotional reactions of gloom and disappointment when they ebb. It would be better for him to receive them gratefully as well as to regard their passing as tests of his resignation to the higher self and of his trust that its inner working is not mistaken. It knows quite well what It is doing in and for him.
