Jor - A poem by Guru Nanak 
Pauri 33 of Japji
See Translations below

Aakhan Jor Chupey Nahi Jor
Jor Na Mangan Den Na Jor

Jor Na Jivan Maran Na Jor
Jor Na Raj Mal Man Sor

Jor Na Surti Giyan Vichaar
Jor Na Jugati Chutte Sansaar

Jis Hath Jor Kar Vekhey Soyee
Nanak Uttam Neech Na Koyee

Translation 1:

No power to speak, no power to keep silent.
No power to beg, no power to give.
No power to live, no power to die.
No power to rule, with wealth and occult mental powers.
No power to gain intuitive understanding, spiritual wisdom and meditation.
No power to find the way to escape from the world.
The one who has the Power in His Hands. He watches over all.
O Nanak, no one is high or low.


Translation 2:

Powerless are we to speak or remain silent
Powerless are we to receive or bestow
Life and Death is beyond our power
Neither riches nor mental turbulence is in our power
Awareness and awakening is not in our power
The path of liberation is also not in our power
The one who has power so He beholds
Says Nanak, in himself none is high or low

In our day to day life, we are governed by our Ego and ever changing moods. This is so as we are bound by Time, Space and Causation. Yet, we in our ignorance feel that we have "power" to do this or do that and become boastful of our "power". This ignorance leads us to feel ourselves superior to others.

In this Pauri, Guru Nanak categorically explains that nothing is in our power. And no one in himself is superior or inferior.
