फूलों के रंग से, दिल की कलम से

The man expresses love for his lover. Couple of examples:

• "I write every day with my heart as the pen, with ink as colorful as flowers, ... "
• "Wherever you went, you always smiled ..."

The amount of praise he showers on her could make any girl blush ... or wonder whether she can live up to it!

जीवन से भरी तेरी आँखें

A very good poetic way of describing the desirability of the lover, particularly if the lover is feminine.

पल भर के लिए कोई हमें प्यार कर ले

A rather naughty means of expressing romantic love.

ज़िंदगी का सफ़र है ये कैसा सफ़र

Simple summary of life, although through the eyes of an unhappy man.

"What kind of a journey is this life
That no one understands, no one learns about."

जीना यहाँ मरना यहाँ

Another Mukesh stunner from मेरा नाम जोकर.
