These days, true friendship are very rare. People often do friendship for their selfish purpose. I have personally experienced this in my school. Modern society's emphasis on superficial relationships and individual pursuits can make it harder to foster lasting friendships. This is one of the reason that makes social media platform so popular among youth. Sanskrit have following to say :
मित्रं प्रीति रसायनं नयनयोरानन्दनं चेतसः
पात्रंयत्सुखदु:खयोः सहभवेन्मित्रेण तद्दुर्लभं
ये चान्ये सुहृदः समृद्धि समये द्रव्याभिलाषाकुला
स्ते सर्वत्र मिलन्ति तत्वनिकषग्रावा च तेषां विपत्
Mitram preeti rasayanam nayanyoraanandnam chetashh
paatramyatsukhadukhhyoh sahabhawenmitren taddurlabham
ye chaanye suhradh samriddhi samaye druvyaabhilaashaakula ste sarvatra milanti tatwanikshagraawaa cha tesham vipat.
Preeti = friendship, affection.
Rasaayan = chemical
Nayan = eye.
Aanand = pleasure.
Chetash = feeling.
Durlabh = found rarely
Suhruda = friend Tatwanikashagraawaa = testing for the true worth. (Nikash means 'Kasauti' a stone which is rubbed by jewellers over a piece of jewellery to determine the puirity of gold. So this process is called 'kasauti par khara utarna)
Vipat = danger
i.e. A friend, whose association with you increases your affection towards him, his presence is pleasing to your eyes and mind, and who shares your good and bad situations equally, is very rare to get. On the other hand your friends, who during the period of your affluence are always eager to share your wealth, are found every where, but the real test of their friendship is at a time when you are in trouble.
The underlying idea is that fair weather friends are available in abundance but will abandon you when you are facing danger and only your real friend will stand by you for helping you. A true friend is someone who supports and helps you, especially during difficult times. It highlights the importance of loyalty and dependability in a friendship, emphasizing that a true friend is one who stands by you not only in happy times but also when you need their help the most.
