After you wake up you probably open the curtains and look outside. You may even like to open the window and feel the cool morning air with the dew still on the grass. But is what you see really "outside"? In fact, it is your own mind. As the sun sends its rays through the window, you are not just yourself. You are also the beautiful view from your window. You are the Dharmakaya.

Dharmakaya literally means the "body" (kaya) of the Buddha's teachings (Dharma), the way of understanding and love. Before passing away, the Buddha told his disciples, "Only my physical body will pass away. My Dharma body will remain with you forever." In Mahayana Buddhism, the word has come to mean "the essence of all that exists." All phenomena--the song of a bird, the warm rays of the sun, a cup of hot tea--are manifestations of the Dharmakaya. We, too, are of the same nature as these wonders of the universe.
