A propos of the quote from Doris Lessing,I turn over this question in; my mind.Thinking is not having  sentences or words passing through our conscious mind like,I envy that person who has just been on a cruise/bought a large house;did I lock the door; is my new neighbour gay;why am I here?

I assume people meditate to stop that mental chatter.If you stop it you may  find a painful feeling hiding.

So what is thinking?My mind goes blank.Is it a conversation with onesself or another?

When we have to make a decision,talking it over enables a seeing of different aspects/by one’s self,thinking may be a kind of confrontation .facing some idea,,,,dwelling on it.

It seems so simple but I don’t know what it is.
