This is an excellent book (the original; I'm not sure about this edition). I have acted as a guide, and the people who I led were very appreciative and seemed to gain a lot out of it. However, it is a challenge to try to use it by oneself, and thus, I feel that it is not as accessible as it could be. I encourage people to try to use it in groups of friends to develop creativity and further mental capacities. I believe it presses into the spaces that keep us from further understanding reality, pushing the boundaries of what we come to believe is reality. In this way, I would also caution that if it is used by the wrong people, in the wrong situations, and not with care and love, it can be harmful. I would contraindicate its use by people who are currently under severe emotional stress. Connect with the boundless love of the Universe anytime you feel the need to, and you will be safe in that warm embrace.
