My sadhana is to meditate for 20 minutes every morning (no exceptions).
"Sadhana means a practice of self-discipline that allows one to express the Infinite within one's self. It is a time each day to notice the patterns that lead away from higher consciousness and to transcend those patterns. Sadhana is a conscious activity. We consciously choose to rise up, to exercise the body , and to meditate. Each day is different. Each day, we are different. every 72 hours all the cells of the body totally change. Sickness comes and goes. Motivation waxes and wanes, but through all the flux of life, through all the variations of the mind and heart, we consciously choose to maintain a constant and regular practice."
