Yet, I read only one chapter and following the advice and instruction to the letter for almost a month.
I am feeling the deep joy from meditating just ten minutes. I know I am not supposed to get attached to this deep bliss feeling, but it validates my efforts.
I read the first chapter a few months back, but did not really start following it until I started reading W. Rahula's What the Buddha Taught and Bhante Gunaratana's Mindfulness in Plain English.
I am deeply attracted to the Theravada Buddhism philosophy. And there is no place of blind faith in it.
So, my serious attempt to meditation started after I learned more about Buddha and his way. I had to try it.
I much more calm and composed. With better concentration and more self-control. Procrastination has left me. And I have insights much easier than before. I am an overally better thinker, now. And I give the credit to meditation.
Good meditation teaching is equipping the practitioner with a toolset with the right tool applied for the appropriate stage of practice.
TMI and Mastering the Core Teachings of the Buddha are necessarily complex because they are treating the entire path toward nibbana as a segmented map of attainment. I can think of virtually no technique which can be applied from the beginning to the end except for very difficult-to-approach techniques such as shikantaza ("just sitting") or the ekayana ("one vehicle") techniques of the Quanzhen ("complete reality") Chinese Buddhism schools. If you think TMI is obtuse try and approach the Shurangama Sutra which is really a mindfuck. But here's the thing: unconditioned existence is a mindfuck so we often need "lesser" graduated techniques to approach the paradoxical nature of reality.
