Crowds create illusions.

As you are now you are just a liquid phenomenon, changing every moment, nothing stable. Really you cannot claim any "I" -- you don't have one. You are many "I"s just in a flow, a riverlike flow. You are a crowd, not an individual yet. But meditation can make you an individual.

Never belong to a crowd; Never belong to a nation; Never belong to a religion; Never belong to a race. Belong to the whole existence. Why limit yourself to small things? When the whole is available.

The mind is just like a crowd; thoughts are the individuals. And because thoughts are there continuously you think the process is substantial. Drop each individual thought and finally nothing is left. There is no mind as such, only thinking.
