Read on this strict 2 days and a half fasting tibetan practice HERE.

I have long wanted to do a nyungne retreat in Toronto at one temple but as I smoke, i could never attend them. Now that I reread the description, i find it sounds quite difficult! I would truly struggle today doing such a practice. They visualize Chenrezig throughout the practice. I am truly taking baby steps in fasting again these days. The nyungne sounds way tough. Maybe I will be able to do it at home one day minus the non smoking.

I think they are not allowed drinks of any sort either....from midday to dawn.
