the connection can snap at any moment

अश्नीत पिबत खादत जाग्रत संविशत तिष्ठत वा।

सकृदपि चिन्त्याह्ना सावधिको देहबन्ध इति॥

अप्पय्य दीक्षित वैराग्यशतके॥५४

aśnīta pibata khādata jāgrata saṁviśata tiṣṭhata vā|

sakṛdapi cintyāhnā sāvadhiko dehabandha iti||

appayya dīkṣita vairāgyaśatake||54

A reminder from the great scholar Appayya Deekshita in his Vairagya Shatakam.

the free translation of the slokam.

=========

Enjoy the fruits of your action

Drink to your hearts content

Eat sumptuous food

Keep awake.. be alert

Sit somewhere if you want

You can choose to remain standing too

But every day, at least once, keep in mind the fact that the connection between your body and the vital force running it is very conditional. 

The connection can snap at any moment without notice..

=========

Life is uncertain.. Enigmatic.. We would continue planning.. but our plans can end at any moment..

I think the good god is keeping absolute control over his creations.. especially human beings by introducing that uncertainty about his existence and sudden demise..
