hi all, and yes you got it right wakeupneo.
concerning how an overload might look like, here's just a little brief sketch for you to watch out not to overload:
around the beginning of last month and after an intense period of sadhana, i turned into a walking human torch like literally burning with shakti flying all over the place.
i was emotionally unstable, ecstatic, depressed, moody, couldn't enjoy the peace of Self enquiry and mindfulness the way i used too, had lots of ups and downs... let's just say that it was very unpleasant.
in order to quiet things down i had to cut down a lot of practices including kechari mudra, decreased practice time as well and exhausted myself physically: lifting weights, walking and running every day, and doing push ups whenever i could, and eating lots of heavy foods...
now i am back into stable land with a few signs of overload at the crown every now and then but it all seems to be heading toward the best in general.
btw other than John Wilder and Gopi Krishna, i know that Sri Atmananda Krishna Menon is another example of those who overloaded to the extreme during their sadhana. (he ended up paralyzed for three days in a row after six months of powerful energetic practices)
guess i might've been headed the same way if i kept on the way i did...
L&L,
Ananda
