I appreciate that you think that opening up spiritually when you are younger somehow makes it easier to make progress, or that you are somehow more likely to benefit. But your writing suggests that you are still attached to ideas of progress and linearity, and you're operating from assumptions about age and how spiritual practices work.
There are countless examples of young people who started meditating at an early age, only to hit walls and abandon their practices for a material life. I've known meditators who began at a young age and are still grappling with the same issues decades later.
How quickly or deeply one makes progress has little to do with chronological age. My spiritual awakening began when I was nearly 39. I am now a psychic channel who has published 4 books and helps people to understand and heal their karmic blocks. Don't assume that someone who is 40 is too brittle to be molded by spiritual practice, or that someone who is 20 is actually ready to do the work.
