Some find their path and light it up to help others find it. If nothing ever died we would be up to our ears in houseflies in no time flat. It is the physical nature of humans to cooperate and compete, love and hate, kill and nurture. Balance is the goal. The Rede is a guiding principle, not an iron-clad rule.
Gardnerian covens are autonomous.
Because of that, initiation is not offered lightly. An honest seeker who is perceived to not be suitable for Gardnerian initiation may be shown other paths, so that more exploration might be conducted. There are no intermediaries. There is no laity in Gardnerian Wicca. Gardnerians relate to the High Priestess and the High Priest as first among equals as well as, in a sense, Mom and Dad.
