“Some people think that meditation means to sit in some special way, but in actual fact standing, sitting, walking and reclining are all vehicles for meditation practice. You can practice at all times. Samādhi literally means ”the firmly established mind.” To develop samādhi you don’t have to go bottling the mind up. Some people try to get peaceful by sitting quietly and having nothing disturb them at all, but that’s just like being dead. The practice of samādhi is for developing wisdom and understanding.”
