Thoughts on preliminary practices:-
1. Sleep (early to bed, early to rise, etc.) - also, we're training to be Awake, aren't we? So utilize the body's natural rhythms for being awake in the ordinary sense.
2. Water (important practical everyday point - could also cover "eating right" and all the rest of it). I've actually been getting eating a bit more in control recently, have lost a few stone weight, and aiming to keep going.
3. Reflection on impermanence. This includes on death, pleasures, my things, relationships, etc., etc.
In conjunction, qigong, and some aerobics and weights for physical health. Mens sana in corpore sano.
