Why do we do whatever we do?

To stay alive and to ensure that life continues?
ಎಲ್ಲಾರು ಮಾಡುವುದು ಹೊಟ್ಟೆಗಾಗಿ ಗೇಣು ಬಟ್ಟೆಗಾಗಿ.

It can't be just that? Or can it?
Does there have to be a bigger purpose?
Either ways it is at least that - मृत्योर्मा अमृतं गमय ।.

Staying alive requires knowing truths - असतो मा सद्गमय ।

Life is long and hard - a tiny bit of beauty adds a lot of joy - तमसो मा ज्योतिर्गमय ।

Survival of just oneself? One's family and friends? One's countrymen? Everyone ?
Where should our allegiance be?
