You didn't mention to whom we are try to explain our ideas. However I try to answer as far as I got your question. If listeners are foreigners, you must be aware about body language of those people whom you are trying to explain. Otherwise, there is no any alternative solution.

How can we explain all our ideas without using and thinking in our mother tongue?
It is not possible in the early stage of our learning a language, but when becoming authority on a language it is possible.
So get this ability step by step without skipping.
