"Be attentive to yourself.
Be introspective.
Live only in your own world.
Do not let yourself become entangled in extraneous matters.
-------------------------------
My two cents ---
The main thrust of this "pearl" is to study oneself only, and not to bother about anything else. The intention here is not to become passive and lazy. In his writings, Pujya Shree Mota has made it abundantly clear that you should do all work that comes to you with diligence and love. Here he is asking us to refrain from entangling ourselves intentionally in somebody else's business. It requires a great sense of discretion. Non-intervention should never be an excuse to hide or promote laziness.
