I have read hundreds of different texts in Sanskrit and many verse have stuck with me. I shall list out 5 that I love absolutely in no particular order.
Let us begin with a Subhashita that talks about their importance.
पृथिव्यां त्रीणि रत्नानि जलमन्नं सुभशितम् |
मूढैः पाषाणखंडेषु रत्न संज्ञा विधीयतॆ ||
On this earth, there are three jewels - water, food and subhashita. But the fool calls pieces of stone, jewel.
One more verse with a similar meaning
भाषासु मुख्या मधुरा दिव्या गीर्वाणभारती।
तस्यां हि काव्यं मधुरं तस्मादपि सुभाषितम्।।
Sanskrit is special and important among languages. In that, poetry is beautiful and Subhashitas even more so.
Now is a verse that talks about being cautious.
अग्निशेषम् ऋणशेषम् शत्रुशेषम् तथैव च |
पुन: पुन: प्रवर्धेत तस्मात् शेषम् न कारयेत् ||
If a fire, a loan, or an enemy continues to exist even to a small extent, it will grow again and again; so do not let any one of it continue to exist even to a small extent.
The next one is about how a hard-working person is.
क्वचिद्भूमौ शय्या क्वचिदपि च पर्यङ्कशयन: |
क्वचित् शाकाहारी क्वचिदपि च शाल्योदनरूचि: |
क्वचित् कन्थाधारी क्वचिदपि च दिव्याम्बरधर: |
मनस्वी कार्यार्थी न गणयति दु:खं न च सुखम् ||
Sometimes sleeps on floor and sleeps on fine bed at other times. Sometimes manages only with vegetables and eats delicious rice at other times. Sometimes wears torn clothes and wears elegant clothes at other times. The person devoted to work does not care about sorrows and joys.
Finally the one I always remember. This talks about the attitude of the wise towards the world.
अयं निजः परो वेति गणना लघुचेतसाम्।
उदारचरितानां तु वसुधैवकुटुम्बकम्।।
The feeling of differentiating people like "He is my own, the other isn't" is for narrow minded people only. For wise and broad-minded people, the whole world is a family.
