How do you think?

As I was thinking about something earlier, I realized that my thinking was in Tamil.. I was surprised at it, as my mother tongue(MT) was different, and the fact is that "people can think well and grasp well only in their mother tongue (MT)"..

When I made a conscious effort to think in my MT, I wasn't able to concentrate, and the thought of me not able to concentrate on anything in my MT, was in Tamil.. So was I always thinking in Tamil?

No...I was thinking in various languages, MT,Hindi,English and Tamil.. The thought language depends on the environment, as well as the topic I was thinking about and not always in MT.

Known Fact: "One can grasp things easily in their MT".
I really wonder in which language will a child of a surrogate Mom, think... Will it think in the native language of the "ovary donor mom" or that of the surrogate mom?

Some times one does not use any language to think.. The thoughts are in the form of pictures, mostly such thoughts arise when you dream...

Some times the thoughts are not in any form.. In the sense they cannot be categorized into any language or pictures.. One would experience it when the "waves" flow in and out...
