Learning about the Merkaba is an esoteric pursuit, it would seem. However, in these changing and expanding times it is a learning of great value. Being able to activate your Light Body can only open up the cosmos to you, enhancing your awareness, experience, understanding, capabilities, healing capacity, insight…and so on.
As a Sound Alchemist you want to ride the leading edge of new information and tools as much as possible. Personal benefits not withstanding, you would honestly be a better healer.
We stand in times when what was once considered science fiction is becoming the norm of living. New ideas, concepts, techniques, and skills are rising up daily. Opening to such a tool can only point toward more useful information and capabilities for your practice of alchemy.
It is worth exploring. Read the resources, watch the videos, find a mentor, do the meditation and the activation, if you feel called. Experience and then decide for yourself the value.
