A sense of profound one-ness, a feeling of the unity of all energy. Superficial differences of role, cast, status, sex, species, form, power, size, beauty, even the distinctions between inorganic and living energy, disappear before the ecstatic union of all in one. All gestures, words, acts and events are equivalent in value - all are manifestations of the one consciousness which pervades everything. “You,” “I” and “he” are gone, “my” thoughts are “ours,” “your” feelings are “mine.” Communication is unnecessary, since complete communion exists. A person can sense another’s feeling and mood directly, as if they were his own. By a glance, whole lifetimes and words can be transmitted. If all are at peace, the vibrations are “in phase.” If there is discord, “out of phase” vibrations will be set up which will be felt like discordant music. Bodies melt into waves. Objects in the environment - lights, trees, plants, flowers - seem to open and welcome you: they are part of you. You are both simply different pulses of the same vibrations.
