Extracts from an article by Roberto Assagioli in [Spiritual Emergency], C. and S. Grof (ed.);

“…Such a state of exalted joy may last for varying periods, but it is bound to cease. The inflow of light and love is rhythmical, as is everything in the universe. After a while it diminishes or ceases, and the flood is followed by the ebb. The personality was infused and transformed, but this transformation is seldom either permanent or complete. More often a large portion of the personality elements involved revert to their earlier state.

“…Most spiritual experiences contain a combination in various proportions of permanent changes, temporary changes, the recognition of obstacles that need to be overcome, and the lived realization of what it is like to exist at this higher level of integration.”

Extracts from: [The Stormy Search for the Self] by C. and S. Grof

“…An individual having a peak experience feels a sense of overcoming the usual divisions and fragmentations of the body and mind and reaching a state of complete inner unity and wholeness; this usually feels very healing and beneficial. One also transcends the ordinary distinction between subject and object and experiences a state of ecstatic union with humanity, nature, the cosmos, and God. This is associated with strong feelings of joy, bliss, serenity, and peace.“…The experience of numinosity has nothing to do with previous religious beliefs or programs; it is a direct and immediate awareness that we are dealing with something that has a divine nature and is radically different from our ordinary perception of the everyday world.“…During mystical experiences, one can feel that one has access to ultimate knowledge and wisdom in matters of cosmic relevance.”
