Craig's a good teacher also imo, here's a little bio:
At just 19, Craig began apprenticing under his teacher David in Southwest Colorado. David, a little-known meditation master, (who lives a private meditative life) guided Craig for 20 years, in the lineage of Sri Aurobindo. This relationship deeply shaped Craig’s life and teachings. During the last 10 years Craig also studied with Adyashanti who guided him through 4 profound awakenings (head, heart, Hara and Kundalini). Upon request from others, Craig began sharing these nondual teachings in Satsang. (Batgap interview https://www.youtube.com/watch?v=UQhzeoVwnjw)
He experienced an intense years of kundalini awakening, often experiencing extreme pain for years (after already having done a lot of practice) which would later transform into bliss if he could surrender to it, as well as experiencing difficulty with motor skills, sleep, memory etc. and worked with many people whom are also going through a similar energy process (whom mostly come to him asking: how can I stop this?).
He also doesn't recommended energy practices at all, because the goal is self-realization/surrender anyways.
So given we already live in a challenging world full of turmoil, poor support systems, terrible mental conditioning/emotional suppression and a complete ignorance of emptiness: focusing on energy practices might just make things harder on yourself as apposed to doing the self-inquiry/doing nothing or perhaps concentration exercises which is almost always recommended and which has you coming into peace and freedom without adding more buzz than what's needed.
I could not really find much on success stories for chelation on OCD, but I am hopeful. For me personally, I found that my gut health needed to fixed dramatically and that improved it a lot. Diet and exercise were massive for it. Learned techniques like the sedona method and ERP useful. Psilocybin mushrooms did seem to have a lasting positive benefit as well, plus they were very effective short term.
It could be the case that heavy metals are the cause of the depression and OCD. However, for most it seems to be mostly from their bad gut health and life style.
