Last 3 books I read were
How the Steel was Tempered , Nikolai Ostrovsky
Petersburg, Andrei Biely
Less than Nothing by our favorite meme philosopher
After such shit (especially the last one), I'm reading I'm a Cat by Soseki Natsume and really enjoying the actual literature.
This was helped by Foucault, right? I read about it in his biography, haven't read it yet. Gonna give it a try soon.
It's a bit confusing, what with the diffusion of sects and so on, but I would recommend starting off with the Dhammapadam which is something like verse parables, or a Life of the Buddha.For the latter I can't give a good enough pdf sadly, but it's quite easy to find, I got my copy for free.
Mahayana Buddhism by Williams seemed nice to me, it explains the various strands from a theological aspect and gives some further readings and explanations on matters of doctrine and even logic (I loved the part on Nagarjuna), and it also gives a grounding on Zen concepts.
Between general Mahayana and Zen I would read Tao-Te Ching if you haven't already read it. It could go at the start as well, it's a ~70 page book that has a very high reread value.
For Zen I'll admit I haven't read Suzuki, but a collection of Dogen's works was very pleasurable and I preferred reading the source on that part since I had the opportunity.
Physical copy of his works I've got also contained haiku and other verse and I can't vouch for the quality of the pdf (that applies to all pdfs I'm linking, sry)
There are other things to read as well, about Hinayana or Vajrayana, but my readings on that are confined on the Tibetan book of the dead, so apart from that I can't recommend anything on those topics.
There's also some Buddhist-influenced fiction, like Kusamakura by Soseki and Kinkakuji and The Sea of Fertility by Mishima, lots and lots of Japanese fiction actually, just that these along with Akutagawa's short stories are among the best imo.
Very important for me is Nishitani Keiji, who should be read after a grounding on Zen and doctrine to get the full picture. He was a 20th century philosopher influenced by Heidegger, and expounded Japanese/Zen philosophy in a 'Western' so to speak manner. Self-overcoming of Nihilism is a profound and underrated book imo, the book I link, On Buddhism, is a very good introduction/exposition of concepts, should be read before Self-overcoming. In general , read the Kyoto School, leave silly politics behind
