This article I found online describes the way I look at it:
Lwa Met Tet
The importance of the “Master of the Head”
Everyone in the world has Lwa. The most significant of the Lwa that may walk with an individual is the Lwa Met Tet. Met Tet literally means Master of the Head. This is similar to what some would consider a Holy Guardian Angel. The Lwa Met Tet of an individual is that individual’s personal guardian. The identity of the Met Tet can be that of a Rada lwa, a Petro lwa, a Gede Lwa, or even a personal Djab the individual has with them.
You already have a Lwa. I didn’t expect mine to be Damballa, but when he entered my crown and settled within, it felt natural.
Worshipping them, serving them… am I a servant to my body when I respect it needs movement and good nourishment?
Am I worshipping my mind like a slave when i journal, or sit down and run some problem-solving methods instead of giving in and letting life push me around?
Am I being somehow more in charge if my body needs to piss, and I refuse?
See what I’m getting at - we are as one with these aspects, our minds, our bodies, our emotions all need certain amounts of care, maintenance, we perform them for basic common sense and maybe even add things on, like working out, eating healthily, for optimal well-being.
Meditating isn’t worshipping your mind and therefore not being in charge - it enhances you.
Same with connection with the Lwa who is your Met Tet.
Can you dip your toe in - I don’t know, you’ll need someone who’s done the course to answer that. I don’t know what deals or arrangements E.A. made for the benefit of people doing the course.
My situation was that a fellow magician who works with unbconventional methods offered to initiate me by bringing my Lwa into me, and I accepted because my spirits all said to do it.
This is where having a method of divination you can rely upon will help you, or to get a reading done.
