Familiarization is one of the five strengths that allow us to practice our bodhisattva discipline of helping others throughout our whole life. This process is analogous to falling in love. When somebody mentions your lover's name, you feel both pain and pleasure. You feel turned on to that person's name and to anything associated with him or her. In the same way, the natural tendency of mindfulness-awareness, especially when egolessness has already evolved in your mind, is to flash on the dharma. You familiarize yourself with it. In other words, you no longer regard dharma as a foreign entity, but you realize that dharma is a household thought, a household word, and a household activity. Each time you uncork your bottle of wine or unpop your Coca-Cola can or pour yourself a glass of water -- whatever you do becomes a reminder of the dharma. You cannot get rid of it; it becomes a natural situation. So you learn to live with your sanity.
