Tranquility of mind
Tranquility is achieved partly by relaxation of the body and partly by holding good images in the mind. The best image to hold in the mind is the image of the Buddha. The body of the Buddha is not present today to behold, we can only imagine the Buddha as a person who is perfectly calm and relaxed. We can also look at a well-painted picture of the Buddha or a statue of the Buddha that depicts the peaceful serenity of the Buddha. We could also imagine the Dhamma as the teaching about tranquility of mind and relaxation of body. We can imagine the Sangha as the followers who are practicing calmness and relaxation. We can also be inspired by group support while practicing calmness and relaxation ourselves, along with others.
