After sitting in full lotus position in my meditation for the last 1.5 years, few day back i found a link http://zenmontpellier.voila.net/eng/lotus/lotuseng.html

in another thread. Going through this link, i found that i have been sitting as shown in figure 13b - which is incorrect - though it was comfortable for me, only numbness occurred in my legs after some duration. Now i have been trying to sit in figure 13a - for that i am doing figure 11 as an exercise and then trying to sit in figure 13a. But it is causing much pain in my legs in sitting in figure 13a, as i try to put the portion from ankle to top of foot at right angles to other leg, as shown in figure 13a, and not in parallel as shown in figure 13b. within five minutes or even less time, a slight pain is starting as soon as i sit in figure 13a and it continues on and on, until numbness also starts along with pain and at that time, i change my sitting posture as we sit in normal sitting to relax my legs.
Also, after my sitting duration in figure 13a, i am finding there is some pain in both my legs during the whole day - this thing has started from the last few days and it is continuing till today, since i am trying for sitting in figure 13a these days.
So question here- does sitting in figure 13b for nearly 1.5 years has hurt my legs already?
the other problem i find is - only in full lotus i am having comfort in keeping my back straight - other postures i tried but it seems that i have to put extra effort to keep my back straight through-out sitting duration and these other postures (except full lotus posture) does not seem stable to me (or may be i am not doing them correctly). what to do now - after 1.5 years of daily meditation, i still do not know in which sitting posture should i sit. This seems like a disaster to me. Should i stop doing meditation - may be i am a totally hopeless case to even sit in meditation, leave aside any concentration? Please suggest. Thanks in advance.
