He may cook his own food, and never touch anyone else's; he may live in the wilderness like a hermit But if he does not enshrine love for the Lord's Name within his heart then everything he does is transitory. Even an untouchable pariah is superior to him, O Nanak, if the Lord of the World abides in his mind. Ang 253 Sri Guru Granth Sahib JI
Salok, First Mehla:
First, purifying himself, the Brahmin comes and sits in his purified enclosure. The pure foods, which no one else has touched, are placed before him. Being purified, he takes his food, and begins to read his sacred verses.
But it is then thrown into a filthy place - whose fault is this?
The corn is sacred, the water is sacred; the fire and salt are sacred as well; when the fifth thing, the ghee, is added, then the food becomes pure and sanctified. Coming into contact with the sinful human body, the food becomes so impure that like it is spat upon. That mouth which does not chant the Naam, and without the Name eats tasty foods
- O Nanak, know this: such a mouth is to be spat upon. Ang 473 Sri Guru Granth Sahib Ji
True is the food, and true are the clothes, of those who chant the True Name of the True One. Ang 53 Sri Guru Granth Sahib Ji
