Today I started, with A TON of incredible humans, Deepok Chopra's, 21 days of Abundance Meditation. I also started reading "The New Meditation Handbook" by Geshe Kelsang Gyatso. I would not say, so far, that this is a "must read" but I'm only on page 35, so I'll keep you posted. AND I'll recap what I read with my own spin below.
Without inner peace, there is no real joy at all. The more we control our mind, the more our inner peace increases and the more joyful we become. Therefore, the real method to make ourselves happy is to control our own mind through the practice of noticing our breath in meditation.
Problems, suffering, and unhappiness do not exist outside the mind-- they are feelings and so they are a part of our mind. Therefore, only by controlling our thoughts through meditation can we permanently stop making up stories that cause our problems and live with inner peace.
