Nhat HanhAction is called karma. And that's your continuation. When this body disintegrates, you continue on with your actions. It's like the cloud in the sky. When the cloud is no longer in the sky, it hasn't died. The cloud is continued in other forms like rain or snow or ice.
Nhat HanhWhat happens in the present moment? In the present moment, you are producing thought, speech, and action. And they continue in the world.
