I would suggest you'll be better off investigating philosophy in your own way than following a curriculum.
The internet allows us to do our own research, follow our own interests and work free of the restraints of the ruling academic paradigm. In an Indian university things may be different but elsewhere a very narrow curriculum is followed making self-study a strict necessity for a broad view of philosophy that would, say, include the philosophy of your wonderful Upanishads.
In the end we all have to study philosophy by ourselves and for ourselves. There are some good online courses worth considering but nobody can read the books for you or do the thinking.
A good philosopher is bound to be a scholar but this would not require attending university. Philosophy was a popular activity before universities were invented. At one time a lay-scholar had a problem with access to texts but those days are gone.
The two books I'd recommend to self-studiers just starting out would be Colin McGinn's Making of a Philosopher in which he discusses his thoughts about philosophy as he was growing up and Paul Davies' Mind of God in which he discusses the problems of philosophy as they arise for physics. Both are chatty and simple. These may not be so useful to an Indian student but they are an easy way in to the subject. You're in the fortunate position of being able to decide your own reading list.
You may struggle to acquire the various skills that one picks up in the process of formal study, research skills for instance, and communication skills in particular. But it's a problem that can be overcome as you go along.
