Ecstasy → It is formed from the Greek "ekstasis" (meaning to stand outside) which is composed of "ek-" (meaning out) and "stasis" (meaning standing). The word describes a state of being outside oneself, often associated with overwhelming joy or delight.
Imagine someone who is so filled with joy that they feel like they are 'standing outside' of themselves — that's the essence of ecstasy.
