Thanks to all for the answers, and double thanks for the metta. When I started I couldn't even sit up for 5 mins., but now I'm doing 30 mins. in the morning and 30 mins. at night. That, plus yoga and walking for my body, seems to be working well. My mind (consciousness, It, whatever...) wants to continue past 30 mins. but I think it would be wrong for my body. I'll just have to wait until my body catches up with my mind.
I think I'm a little shell-shocked from having just read 'Mindfullness In Plain English' on the web and th author said "most beginners, when they start to meditate are gung-ho and meditate for 15 hours a day". I'm lying on the floor with a damp rag on my head going 15 HOURS A DAY??????
I can remember, when I was with the RZC, sitting for 50 mins., walking for 10, sitting for 50, etc. For days upon end. I'm a bit sad to think I'll never get back to that/ Ah, well, as that famous Buddhist monk said, "whatever".
