I will be taking a Vow Of Silence and Fasting from Friday 9.30 12p to Sunday 10.30 12p

No Alcohol.
No Caffeine.
No Cannabis.
No Food.
No Internet.
No Masturbation.
No Media.
No Sex.
No Social Media.
No Speaking/Talking.
No Tobacco.

Other than basic metabolic functions, drinking water, showering, using the bathroom, and sleeping, I will be doing nothing other than sitting Zazen.
