The word TATHAGATA used for Gautam Buddha has two meanings.
One meaning I have explained to you: it means the man who trusts existence and its suchness.
Whatever happens, good or bad, misery or blissfulness, he remains unperturbed. He says it is the suchness of things. There is no need to be disturbed by suffering and there is no need to be disturbed by blissfulness. All these are natural phenomena. You have to remain aloof. That is one meaning of TATHAGATA.
There is another meaning also, and that other meaning is significant.
TATHAGATA means a man who comes like a breeze and goes like a breeze.
Literally it means, "thus came, thus gone" — he does not wait for your invitation.
Suddenly he comes, and he does not wait for you to prevent him; suddenly he is gone, but he has left behind an experience of coolness and calmness and tranquillity.
That calmness, coolness, serenity, silence, declare more loudly than anything else to the whole existence that a buddha has arrived, that now all the priests are in danger, that all the politicians are trembling inside.
All those who are living on lies are scared to death. Truth has such power. It never harms anybody but it makes the whole fabrication of lies around the world tremble. A single man of truth is enough.
