Hira Ratan Manek’s sun gazing schedule is kind of a connect the dots method for the wider audience. It seems that some of us do well with a more intuitve approach. I am one of them. I just do it til it feels right. I often sense the urge to yawn or some other signal and take that as a sigm that my quantu bath is done. You can set up an intent for your body to signal you prior to the session in such a way. It seems much more powerful though to follow the bare earth method. I find a rock and stand on it with my bare feet. The bonus in this elevated perch is you get to feel like an ancient tribal warrior (in semi urban attire).
