J. Krishnamurthi - Where to start?

I saw some quotes from him on Instagram and followed their page. The more I read his quotes, the more he makes sense. My readings into religion are very limited but if I really have to compare, I can compare him only with Swami Vivekananda.

So, I am thinking of reading some book of his. Not interested in any sort of self help or daily life tips kind. The real philosophical stuff is what I want. So, recommend me some book to start from.
