فلسفه و عرفان ،جامعه شناسی،روانشناسی

Feelings of limitless horizons opening up to the vision,     the feeling of being simultaneously more powerful and also more helpless than one ever was before,
    the feeling of ecstasy and wonder and awe,
    the loss of placement in time and space with, finally,
    the conviction that something extremely important and valuable had happened,
     so that the subject was to some extent transformed and strengthened even in his daily life by such experiences

               Abraham Maslow
