If you are taking time off to let the chronic injuries heal over Christmas, but looking for some brain food as well as the usual heart-attack-producing fare, may I suggest:
Daniele Bolelli’s Lectures on Taoism
Daniele Bolelli is a university professor ,teaching comparative religion and a number of other subjects. He also trains in jiu jitsu and MMA, has his own podcast, The Drunken Taoist, and has appeared on The Joe Rogan Experience podcast several times. His lectures are accessible and entertaining, delivered in a strong but endearing Italian accent. Taoism is difficult to access but he does a pretty good job. Under $10 for over 7 hours of interesting stuff.
Dan Carlin’s Hardcore History – Wrath of the Khans
A spellbinding account of the exploits of Genghis Khan and his extended family, masters of thirteenth century military strategy, at one stage ruling from Eastern Europe all across Asia to the easternmost parts of China, displaying an appetite for domination, ruthlessness and bloodshed that makes Hitler, Stalin and Pol Pot seem like bashful amateurs.
(The above link is to an accessible site for download called podbay.fm. Dan Carlin has his own site. The other stuff there is excellent listening as well).
Books – two texts on meditation
Waking Up; A guide to Spirituality without Religion – Sam Harris
That ought to keep you out of trouble and help to start the new year pumped for training.
