PLEASANT Vs BENEFICIAL

  SUBHASHITHANI:633

It is easy to have people saying what is palatable to us; But difficult to get people who will say what is beneficial in the long run,even if it is unpalatable initially. Ravana had the good luck of people advising him what was in his best interest. but he wouldn't listen and finally lost everything.
We have two identical slokas in Ramayana describing this aspect of human life. 
Maricha to Ravana:

सुलभाः पुरुषा राजन्सततं प्रियवादिनः।

अप्रियस्य तु पथ्यस्य वक्ता श्रोता च दुर्लभः।।3.37.2।।
राजन् O king, प्रियवादिनः sweet tongued, पुरुषाः men, सततम् always, सुलभाः easy to find, अप्रियस्य unpleasant to hear, तु but, पथ्यस्य salutary, वक्ता speaker, श्रोता च audience, दुर्लभः is difficult to find.
O king, it is always easy to find men who speak pleasing words, but it is difficult to get a speaker and a listener who use words unpleasant (to the ears) but beneficial (in life

Vibhershana to Ravana:

 सुलभाःपुरुषराजन् सततंप्रियवादिनः ।
अप्रियस्यचपथ्यस्यवक्ताश्रोताचदुर्लभः ।।6.16.21।।
 राजन् O king, सततम् always, प्रियवादिनः who speak pleasingly, पुरुषाः men, सुलभाः are easily found, अप्रियस्य: that which is unpleasant, पथ्यस्य: good words, वक्ता: speaker, श्रोताच: listener also, दुर्लभः difficult.
"O King Those who speak pleasingly are always easier to find than those who speak unpleasant but good words. Listeners of unpleasant words (though good) are difficult (to find)."
There  is a popular subhashita from Hitopadesa with similar thought but slightly different focus. 

उपदेशो हि मूर्खाणां, प्रकोपाय न शान्तये।
 पयःपानं भुजडाग्नां केवल विषवर्धनम्।।
Upadesho hi moorkhanaanaam  prakopaaya na shaantaye.
Payah paana bhujangaanaam kevalam visha vardhanam.
Advice is of no use to a fool. Instead of placating him, it will only anger him more. If you let a snake drink milk, it will only lead to more venom.
