@hustlerbear81 will check it out. I am also wandering if it is necessary to level them? Everybody is doing vipasana which seems to be the most advanced, does it matter in meditation? Should someone start from a less advanced one?
@no_name_user_me i suggest you look at this book, The Mind Illuminated: A Complete Meditation Guide Integrating Buddhist Wisdom and Brain Science for Greater Mindfulness, this has different levels of mediation going from Beginner to Expert.
