What difference is there of a cell and a human being? A cell ingests and excretes, sends messages, handling affairs that a cell must handle. Likewise, a human carries out the same process, just on a larger scale. We have messengers to inform, food that we ingest and excrete. We have establishments for the purpose of taking care of emergencies that spring up, with ambulances, fire trucks, police cars, which respond to calls of distress, what ever they may be.
All that exists — be it a block of wood which grew from a tree, or a house that came from trees which humans have taken a rearranged in such a manner as to utilize the wood for an alternate purpose — is all one happening. A single, continuous process. There is no difference between this or that, a chair and you. All is of the same existence in multiple states. When it rains, there is no rain. It is the process. When the wind blows, there is no wind and no blowing.
It is one thing to have knowledge of this concept; another to live in it.
