Erkhart Tolle speaks about where mental illness falls in universal consciousness. Pretty much suffering is a natural part of spiritual awakening. In my case, it took emotional Trauma and physical stress for my Kundalini to rise. So I see some truth in it.
I had also been diagnosed with Major Depression that came from Hypothyroidism. So I was going through several antidepressants during this time.
For me, the traumas and stress have been a blessing. I have grown up a lot in the last Eleven years. Not only in maturity but spiritually too. I know myself a lot better now than I did before my Awakening.
