Your life has already begun, and you can start living in the moment right now.
Everything you need to live mindfully and completely is already within you.
Doing your job, maintaining personal discipline, and developing devotion toward fellow sentient beings and the care of the world are ideal arenas for practicing mindfulness and letting go of attachments.
Zen meditation, or zazen, is simply but mindfully sitting to cultivate full awareness.
Meditation is difficult because the mind is in the habit of attaching to thoughts, feelings, ideas, and opinions. Everyday sitting will gradually train your mind to observe rather than attach.
