Bahut Pehle Se, Un Qadmon Ki Aahat Jaan Letey Hai, Tujhe Ae Zindagi, Hum Duur Se Pehchaan Letey Hain

1. 
Bahut Pehle Se,
Un Qadmon Ki Aahat
Jaan Letey Hai,

Tujhe Ae Zindagi,
Hum Duur  Se
Pehchaan Letey Hain.......

2.
Tabiyat Apni
Ghabraati Hai
Jab Sunsaan Raaton Mein,

Hum Aise Mein
Teri Yaadon Ki
Chaadar Taan Lete Hain.....

            ........ Firaq Gorakhpuri

========================

Such a simple words roped for enormous depth

I am totally confused,
how to translate
the difference between
Hindi words, 

Jaan :  know?
Pehchaan :  know?

actually both are miles away,

Also the spine of first couplet

Please suggest me
English translation
(one word please) .

===================

The literally meaning : 

1.
bahut : long
Pahle se : before
Un : your's
Qadmon : walking step
aahat : noise
Jaan : to know?
Letey Hain : we be able to do.

Tujhe :  You
Ae Zindagi :  the life
Hum :  We
Duur :  long distance
Se :  from
Pehchaan : know accurately Letey Hain : we be able to do. 

Long before your arrival,
we guess your
walking step noise,

You being my life,
We know you
from a long distance 

2.
Tabiyat : state of mind
Apni : mine
Ghabraati : perturbed  disturbed
Hai : happen
Jab : when
Sunsaan : lonely
Raaton : nights
Mein : with in

Hum : We
Aise Mein : in this situation
Teri : your
Yaadon ki  : memories as
Chaadar :  sheet of cloth
Taan Lete Hain : straight up 

When I feel perturbed
in the long lonely nights,

In this situation,
I take the refuge of
your old memories.

====================

B : The feeling or correct meaning

1.
My love,
You are my life,
Without you,
I am  like a lifeless creature,

Merely by thinking about you,
I become a fully awaked
and a happy person

That is why,  I always gauge  your presence (not physical) from a very long distance. 

2:
When i do not feel good
in long lonely nights
without you,  my love

I take the refuge in your lovely memories........

I salute you,  Firaq Sahib
