I read about how a lot of folks complete these in 15 minutes. I can too. But I think it's too fast.
I know it says, By this timing you will know if you're going too fast or too slow. But then it says, Do them slowly with deep concentration.
Contradictory really.
It takes me about 30 minutes. I don't see the point in whipping thru them. I'm not so sure PY intended to do all these in 15 minutes, my bet is someone changed it.
Perhaps it depends on how many times u practice each separate 'exercise'. Many times I find it difficult to fit in all the practices. It seems like the 'demands' on our time force us to make choices. I would say that it is good u have made the energization exercises a priority. That is an inspiration to us all. I remember Brother 'Turyananda' saying he practiced them more then twice a day. I think the guidelines were set up so we wouldn't cut ourselves short. Not as 'rules' to shorten our practice if we so choose to make it longer.
