Try googling 45 Days to Awakening course, a new and improved version of the Finder’s Course. Their data shows something like 65% of people reach that state after 45 days, up to 85% after a second course for total of 90 days. It sounds way too good to be true and I didn’t believe it myself until I did it and it worked for me, and then for several friends I convinced to take it. It took me over 90 days to get there (had to keep practicing the meditation styles that worked best for me) but then stabilized. One of my friends transitioned literally on her first meditation on day one. Good luck on your journey!
