Atman is the ever present reality. Yet, because of ignorance it is not realized. On destruction of ignorance Self is realized. - Sri. Adi Shankaracharya
Thousands of thoughts run through our mind every day. Some of them are helpful, and some of them aren’t.
Never take your thoughts too seriously or you will get into trouble- though I have knew this rationally but I practiced just the opposite. I believed in my thoughts very seriously particularly those which were drilled ingrained into me by my family and community consciously and unconsciously.
