The Wisdom Library is great!

I use the Wisdom Library all the time:

It pulls together a whole bunch of different sources on Indic spirituality, so you can search for a term, a text, or an idea and see the Buddhist, Hindu, and Jain takes all in one place. It’s got a maximalist vibe, so there’s often a lot of repetition and redundant info, but that’s fine for research.

It’s a passion project by Gabe Hiemstra of the Netherlands. He’s got a Patreon, so why not practice dana?
