One of the basic kabblistic methods for meditation is through the use of the imagination, which works quite well for working with different forms of energies that are often used to give definition to characteristics of angels.

Not long ago I heard from a dear friend whose son had been the victim of a freak accident. He had been hit in the back of the head by a golf ball. His recovery was not going well, and a blood clot in his brain was causing pressure that potentially could paralyze him for life, or worse.

High risk surgery with possible brain damage was a fast approaching option that everyone wanted to avoid.
