I am new on Indian Guitar(also a guitar beginner) I heard this song Tere Bina, and its really cool

and found its guitar chords here at

Abhijeet Sawant - Tere Bina chords submitted

but unable to get the strumming right (as in the original song there are lots of other instruments also, which makes impossible for a beginner like me to get correct strumming from the original song)

Here is the original song


so if anyone could point me to a video of playing this song on guitar will be great, or explain how i can achive.
