Diet in Sikhism - Guru Granth Sahib

Sikh intellectuals believe that the issue of meat and vegetarianism is addressed in one section only of the Guru Granth Sahib:

—

First Mehl:
The fools argue about flesh and meat, but they know nothing about meditation and spiritual wisdom.
What is called meat, and what is called green vegetables? What leads to sin?
It was the habit of the gods to kill the rhinoceros, and make a feast of the burnt offering.
Those who renounce meat, and hold their noses when sitting near it, devour men at night.
They practice hypocrisy, and make a show before other people, but they do not understand anything about meditation or spiritual wisdom.
O Nanak, what can be said to the blind people? They cannot answer, or even understand what is said.
They alone are blind, who act blindly. They have no eyes in their hearts.

They are produced from the blood of their mothers and fathers, but they do not eat fish or meat.

On the view that eating vegetation would be eating flesh, first Sikh Guru Nanak states:

AGGS, M 1, p 1290. —

First Mehl:
Punjabi: ਪਾਂਡੇ ਤੂ ਜਾਣੈ ਹੀ ਨਾਹੀ ਕਿਥਹੁ ਮਾਸੁ ਉਪੰਨਾ ॥ ਤੋਇਅਹੁ ਅੰਨੁ ਕਮਾਦੁ ਕਪਾਹਾਂ ਤੋਇਅਹੁ ਤ੍ਰਿਭਵਣੁ ਗੰਨਾ ॥

O Pandit, you do not know where did flesh originate! It is water where life originated and it is water that sustains all life. It is water that produces grains, sugarcane, cotton and all forms of life.

On vegetation, the Guru Granth Sahib described it as living and experiencing pain:

—

First Mehl:
Look, and see how the sugar-cane is cut down. After cutting away its branches, its feet are bound together into bundles,
and then, it is placed between the wooden rollers and crushed.
What punishment is inflicted upon it! Its juice is extracted and placed in the cauldron; as it is heated, it groans and cries out.
And then, the crushed cane is collected and burnt in the fire below.

Nanak: come, people, and see how the sweet sugar-cane is treated!

The first Sikh Guru—Nanak Dev—said it was pointless to debate the merits of either not eating or eating meat in the context of religion, as maintaining a strict diet does not make one blessed or elevate one to a superior status, spiritually or otherwise, over another. Being a member of a religion incorporates not merely one's dietary customs but the entire way in which devotees govern their lifestyle. He advocated a lifestyle consisting of honest, hard work and humility, focus and remembrance of God, and compassion for all of humanity and God's creation all around. These three key principles take precedence over one's dietary habits.
