What precisely would an Indian circa 1914 mean by "hindustani."?

Would Bangladesh and Pakistan be included in this term . More specifically, the person (JC Bose) I am studying said, "Be an Indian first...Make that part of your religion. Outgrow provincialism. Try to think in terms of the vast continent of India. It is stupid to imagine that one province is better than another; it is worse than folly to think that a man of one province is naturally superior to that of another. In the New India, there will be no Panjabis, no Marhattis, no Bengalis. We are all going to be Hindustanis. Do you understand me clearly?" Would you interpret this to mean that Bose envisaged a single India with both Muslims and Hindus? Thank you.
