I am writing for this brother , he is now 38 yrs old and not working . He showed mental instability when he was 17 yrs old when he failed to get through entrance examination , after that he was depressed and he joined in an ashramam for about 1 yr , he came back with severe cold and started living with us . Initially he was ok and got engaged in spiritual activities but slowly character started changing and he gets violent , some of his unusual activities include taking bath for half of a day
