Pauri, Pauree or Pouri is a Punjabi term for a 'step' (staircase), paragraph or section of verse in the Sri Guru Granth Sahib, which the Sikhs regard as more than a holy book. The Sikhs treat their sacred scriptures as their living Guru. The holy text is also referred to as Gurbani or just Bani. Each paragraph of normal verse is called a Pauri or a Shabad. Various other words are used for special sections of Gurbani.
"Paurees" are a form of stanzas. They also contain the essence of the Vaars. Literally meaning ladder, rung, step or stair it is a form of stanza adopted for Vaars. They generally consist of 6 to 8 lines each. Stanzas of Baabaa Nanak's Japuji are also traditionally called Paurees. Traditionally, Raagees are supposed to conclude Kirtan with singing of a "Pauree" from Raagas Bilaaval, Kaanraa etc.
In the major religions of the world stairs or ladders are seen as a metaphor for ascending to Heaven. The Sikhs Gurus, including the SGGS, are seen as the guide or way for a Sikh to attain Moksha or liberation, by following Gurbani and living a life of service to others.

One of the biggest musical hits of all times in the West, during the so called age of Aquarius when many young Americans males grew long beards and hair (this user included) was the call to travel a different road toward Heaven - "Stairway To Heaven" by the group Led Zeppelin .

Beckoning people to take a different road.
