they never break rules

प्रळये भिन्नमर्यदाः भवन्ति किल सागराः।
सागराः भेदमिच्छन्ति प्रळयेऽपि न साधवः॥
चाणक्यनीति
praḻaye bhinnamaryadāḥ bhavanti kila sāgarāḥ|
sāgarāḥ bhedamicchanti praḻaye'pi na sādhavaḥ||
cāṇakyanīti
പ്രളയേ ഭിന്നമര്യാദാ; ഭവന്തി കില സാഗരാ:
സാഗരാ: ഭേദമിച്ഛന്തി പ്രളയേപി ന സാധവ:
when the deluge at the end of a yuga sets in, 
the oceans throw to winds all the rules of propriety
 and 
transgress their boundaries to gobble up the entire land area

Maybe the oceans were just waiting for an opportunity to break the rules. 

 But noble men will never never break the rules.  
No even can shake them  
and they will behave with equanimity and poise even
 when the greatest of catastrophes  overtake them.
