I've read on lot of websites that if someone cannot perform Padmasana properly Vajrasana can be a good substitute.
So, it is possible to reach Asana Siddhi, to sit 3 hours in Vajrasana if you progress slowly?
I mean, you won't have any problems from that? The body can adapt completely? Just because in this kneeling posture your whole bodyweight is on the feet and calves.
I can already sit in this posture 45 minutes without any endurable discomfort. So, is it a realistic goal to achieve Asana Siddhi with this posture?
Thanks for the answers!
