Road is the destination, thus you arrive a changed man, ready for the Indian sub-universe to experience and mold you further.

And specifically on this, clashing with a very exotic cultures and mindsets along the way, forming unexpected intense interactions and experiences that you will remember for the rest of your life.

I've done a similar thing to this since this specifically wasn't possible anymore without crossing battlefields and risking kidnapping and death - backpacking around India for 6 months together. No real destination or plan, just 1 thick Lonely planet book covering whole country in the backpack (this was 2008 and 2010), return ticket and fixed budget in cash.

Came back a bit different, dare I say in some ways enlightened person. Experience cannot be explained to others by mere words, but other folks who experienced similar understand without a word.
