原唱原版歌词（即北印度语，用英文字母写成）
Ho Oo..., Ho Oo..., Hooo..., Ho.. Ho...
Kaise Mujhe Tum Mil Gayi, Kismat Pe Aaye Naa Yakeen
Utar Aayi Jeet Mein, Jaise Chaand Utar Ta Hai
Kabhi Haule Haule Dheere Se
Gun Guni Dhoop Ki Tarah Se Tarango Mein Tum
Chhoo Ke Mujhe Guzari Ho Yuh
Dekhu Tumhe Ya Main Sunoo, Tum Ho Sukoon
Tum Ho Junoon..., Kyun Pehre Raat Aayi Tum
Kaise Mujhe Tum Mil Gayi, Kismat Pe Aaye Naa Yakeen
Main To Yeh Sochta Tha, Ke Aaj Kal Kuch Bataane Ko
Fursat Nahi Phir Bhi Tumhe Banaake Woh
Meri Nazar Main Chadh Gaya, Ruit Pe Duaa..Aur Ban Gaya
Badle Raaste Jharne Aur Nadi, Badli Deep Ki Tin Tin
Chhede Zindagi Dhun Koi Nahi, Badli Barkhaa Ki Rimjhim
Badlengi Rituein Ada..., Par Main Rahoongi Sada...
Usi Tarah Teri Baahon Mein Baahein Daal Ke Har Lamha Har Pal
Zindagi Sitaar Hogayi, Rimjhim Malhaa Hogayi
Mujhe Aata Nahi Kismat Pe Apni Yakeen Kaise Mujhko Mili Tu

你怎么会来到我身边
How was it that you came to me
幸运到我不敢相信
How blessed l am,but it's hard to believe
你踱步于生命的湖畔…
You descended upon life's placid lake…
如皎洁皓月般
like a rare Moon,
柔缓
slowly,
轻柔
gently
Sanjay Singhania(阿米尔·汗)
(男唱)
就像冬日暖阳下
Under a winter's Sun,
温暖的旋律…
like a warm melody…
你爱抚着我
you have caressed me,
我深深的迷上了你
l am enthralled
是你赋予我平静我为你而存在
In you,my peace.You are my passion
相逢恨晚啊？
Why didn't find you before?
你怎会来到我身边？幸运到我不敢相信
How was it that you came to me…haw blessed l am, but it's hard to believe
(男唱)
曾经我相信
And once l believe,
是因为造物主发现…
that the Creator finds…
他激情不再了
His urge no more
所以…
And then…
他创造了你
He created you
此刻在他的光辉笼罩之下…
And now He is revealed to me…
他向我泄露天机
in all His glory
(女唱)
世界万物瞬息万变
Pathways,streams and rivers all change
唏嘘灯火亦闪烁之
Glimmering lamps cast lights of change
当改变敲响生命的音符
When the change strikes life's rhythm
雨的旋律也会随之变化
The rhythm of the rain will also change
季节也会变化
And the nature of seasons will change
但是…
But l shall forever be…
我心永恒
the same to you as l've been
亲爱的，我们手挽手
Arm in arm,with you my mate,
每一刻
every moment,
直到永远
always
(男唱)
音乐的合声让我的生命为之动容
Chords of a music touch my life,
我能感受到生命中新的旋律诞生
l can feel new tunes coming into life
但我仍然难以相信…
But l still can't believe…
我太幸运
how llessed l am,
你怎会来到我身边…
how you came to me…
