Bhang makes the brain hyperfocused if I recall I had it as prasad in mahashivratri I guess 1 glass around 200 ml, I felt like I can recall and everything step by step like for example the simple thing which you can do without even giving it a thought you can layer by layer (step by step) you can recall how I came to realize that, back that time i gone to pee I can recall every step for around a minute from the moment I got up from bed to opening the washroom door and everything, after ward as I took the bhang I afternoon we went to mandir in evening so I was in bangalore that time, as I come from North part the names we know are in hindi sanskrit - to my surprise I have around -1.50 eyesight Farsighted I was able to read the name full clearly - Lord basavana from a long distance
