Meditation is the act of engaging in thought or contemplation; reflection. The term itself has no direct correlation with any specific religion.
For me, meditation is the very center of religion. The word religion means for me scripture, ritual, rites of passage, tradition, and so forth. Meditation leads to a direct contact with the divine. Religion without meditation is like a river without water. Dry. Desolate. Empty of life.
