For the most part all you need to be able to do is sit on the floor. Well, that and lead a moral (Sila) life.
People charging for 'mindfulness' apps and products really grind my gears!
Dharma Seed [0] is a website (and there are iOS/Android apps) containing hundreds of free to access Dhamma talks.
“People charging for biology textbooks really grinds my gears, you can just walk outside and look at trees or read free content online!”
Indeed, you sure can!
He does still have some decent "pithy one liners" but if I remember right, he didn't stay in a philosophical lane and was known to indulge in pop culture conspiracies and his own pet theories (based on excruciatingly little but conjecture and didn't really respond to criticism of it)
I've honestly started to consider it a little bit unbecoming to compare people to McKenna. He's a major contributor to a romantic and oversimplified/inaccurate understanding of things like shamanhood and the roles drugs played in ancient societies, so it's probably a good thing people don't talk about him like they used to.
Almost kind of the antithesis to Watts in my mind, but seemingly from the same side of the fence: McKenna was all about what he thought, and Watts never gave me the impression he even had an agenda for me to believe in, rather wanting to help people explore the world he'd discovered, he labored to find the words to depict, not to convince.
McKenna, possibly a YouTube downloader and a playlist like https://www.youtube.com/playlist?list=PL83BE388A2A15A7E1 - some are short, but many are hour or two long full lectures. and https://www.youtube.com/playlist?list=PLyhHqyVEk0F-k42F1nAh6...
(I didn't realise how many lectures he did; many of those I haven't heard, and many of the ones I have heard aren't mentioned in those playlists).
(For the unwary, "Alan Watt", Scottish conspiracy theorist https://archive.org/details/The_Alan_Watt_Collection is somebody else).
