Shanti summed it up very fine. Emc added well too.
some more:
when energy gets too high: no sleep, extreme tiredness, too much out of control thoughts, can't stop
when silence gets too much: no mind, no sense, no movement, no breath, no blood
Not that anything of this is good or bad, as these are transitory symptoms. But within modern life styles, like in a city, these things seem strange and unnormal and can create "unnormal" functioning for some time.
But the end of the tunnel of all of these symptoms is great. Energy blows out blockages and ego, life becomes paradise, expression of the inner becomes effortless. Silence dives into peace and bliss and reveals this as you.
