i have heard in sureshnandjis satsang to keep leaves of ashoka trees in the studuroom door and also keep feather of peacock in his study room this will help him to attain concentration.
u try one thing while he is in deep sleep just chant "i am concentrating on study , i am getting sincere for abt 21 or more times at his back side of head by gazing" this will directly enter in his subconscious mind and u will find a change in his behavior "
i have heard this in bapujis satsang to use sankalp shakti in good faith.. have a look at the small effective video satsang series http://ashram.org/MultiMedia/Audio/...fault.aspx
