Chaitanya means the living force. You and I can move, but a table cannot because it has no living force. Not only movement, but resistance is also a sign of living force. Chaitanya means activities, Amrita means immortal, and Charitra means character. There is no activity without living force. The material condition has living force but is not Amrita, immortal. Chaitanya Charitamrita, then, means the Character of the Living Force in Immortality.
But how is this displayed? It is not displayed by you or I—none of us are immortal in these bodies. We have living force and activities, and we are immortal by nature and constitution. But the material condition into which we have been put doesn't allow these qualities to be displayed. It is stated in the Katha Upanishad that eternality and living force are characteristic of both ourselves and God. But God and ourselves, although both immortal, are different. The living entities have many activities, but have a tendency to fall down. God has no such tendency. He is All-powerful. He never comes under the control of material Nature, because material Nature is only a display of His energy.
