The Dhammakaya is as the crossing bridge between the bank of Relative Truth and Absolute Truth. As it is said that he who is in the first state of Dhammakaya is he who stands on both banks of the river of life. Then he must learn to balance himself well (by always being with his centre).The Theory of Middle Way or The Majjim-magga was very famous in the time of Nagarjuna, the first abbot of Nalanda, the greatest Buddhist University in the time of Gupta Dynasty of ancient India , around c.150-250. It is the latest and the most famous Buddhist Theory concerning “The Dhammakaya” and “The Middle Way”. But, please be noted that the Middle Way is not the theory of the great Nagarjuna. For it is the very principal of Buddhism of Lord Buddha. The words “majjima-pati-pata” that is the main principal of Buddhism and known to the world of philosophy means to go directly, firmly with strong determination through the Middle Way. And it must be only by meditation practice. So, “meditation in action” is the meditation concerning the Middle Way. It is because meditation will lead the practitioner to the effective and practical peace inside. For he who practices meditation can gain peace, earn peace, can survive his life in the petals of peace and can put his peace on every step he walks.
