In Which ancient writtings , Shlokas , Books we find more description about Human Mind ? eg. description of Human Mind's characteristics , qualities, It's strength and weakness etc.?
What texts gives advice to our mind and guides us about our good behaviour in society? For example , A 15 th century saint from western India (Deccan) named "Ramdasa" written a book advising our mind. Name of the book is "Manache Shlok" Or Shlokas for Mind.
Note- Although all our texts including Gita is grand advice to ourselves ,our mind. I want specific writtings about Human Mind.And my question is more philosophical rather than scientific.
