personal opinion about Merkaba:
I've bin checking out Merkaba & Flower of Life.
Especially Drunvalo and i have some, i dunno, issues with it
First, i believe there is something like the golden ratio and some kind of spiritual thing about life and that we lost contact with it. And the link between sprituality and geometry is interesting.
But... that you can travel to the 4th dimention after 18 breaths and some meditation... i don't know about that. Drunvalo is really serieus about this and his story about the group meditations in hawaii and other places so he could re-open some kind of portal for gold-coloured energy to flow again.... i'm a bit sceptic about that to.
So all in all, i find it a verry interesting filosofie and way of thinking, but on the other hand i am sceptic about a few things.
I'm wondering how you feel about the Merkaba, do you follow all that or do you have some questionmarks yourself about it?
