Spiritual practice, whether alone or with a group, can be conducive to interaction with intangible reality. Connecting to wisdom internal enables connection to reality beyond.
Internal wisdom is supplied by the soul, and thoughts channeled through soulful evaluation reflect spiritual connection. The physical actions that accompany spiritual practices extend the effects of the connection. The emotional depth of the concentration on spiritual connection can invigorate the connection. The intellectual quest to fathom the intangible invites contentment. Nourishment of the desire to have impact is attained.
When group worship is sincerely performed, the group can enrich each individual. When group worship is performed perfunctorily, the experience can alienate or bore. When group worship is forced, the experience can be blocked inwardly or can be traumatic.
Group worship that is spontaneous sometimes enriches, but sometimes incites. Group workship that decries other groups is worship misguided. No group has access to divine revelation over any other group. No group!
Spiritual connection, the link to intangible reality, is the historical practice for tying human endeavor to energy of the expanse.
