The Guru is the ocean, and all His Teachings are the river. Bathing within it, glorious greatness is obtained.
ਨਾਨਕ ਜੇ ਸਿਰਖੁਥੇ ਨਾਵਨਿ ਨਾਹੀ ਤਾ ਸਤ ਚਟੇ ਸਿਰਿ ਛਾਈ ॥੧॥
naanak jay sirkhutay naavan naahee taa sat chatay sir chhaa-ee. ||1||
O Nanak, if the shaven-headed ones do not bathe, then seven handfuls of ashes are upon their heads. ||1||
Translation by Dr. Sant Singh Khalsa
In plain words
Some try to become holy by punishing their own bodies. They turn away from clean water, live on what others throw away, and leave their mothers and fathers behind, while their families cry out in sorrow.
No one lights a lamp or makes an offering for them when they are gone; where will they go? The holy places give them no shelter.
They are not yogis or followers of Shiva, and they are not Qazis or Mullahs. They wander lost and ashamed. Only the Lord takes life and gives it back; no one else can protect anyone.
The jewel came out of the water when the sea was churned. The sixty-eight holy places were set up, where festivals are kept and hymns are sung. Muslims bathe before they pray, and Hindus bathe before they worship; the wise always bathe. At birth and at death, water is poured on the head.
O Nanak, those who turn against life do not like to hear these words.
When the rain comes, everyone is glad. Water is the key to all life.
When it rains, the corn grows, and the sugarcane, and the cotton that clothes everyone.
When it rains, the cows have grass to graze, and the milk is churned into butter. With that ghee, feasts and worship are blessed.
The Guru is the ocean, and all the teachings are rivers. Bathe in them, and you are made truly great.
O Nanak, those who will not bathe carry only handfuls of ashes on their heads.
You don't reach the One by fleeing life — Guru Nanak rejects a holiness that mortifies the body and abandons family, and celebrates instead the goodness of water, rain, and honest living, with the true bath being the heart washed in the ocean of the teaching.
The deeper layer
This verse says you don't reach the One by turning against life. You reach the One by living well, loving life's gifts, and washing your heart in the Guru's teaching.
It's the longest shalok, short verse, in this set, and it needs careful reading. On the surface, Guru Nanak is criticizing one group of his time. They tried to become holy by punishing their own bodies, refusing clean water, living on scraps, and walking away from their families. The words are sharp, the way religious debates often were five hundred years ago. The right way to read it today isn't to carry forward scorn for any group of people. It's to take the good lesson Guru Nanak is standing up for underneath. That lesson is one of his deepest beliefs.
Here it is. You don't reach the One by turning against life. The way he criticizes runs away from family, punishes the body, and treats everyday gifts like clean water, a home and honest food as things in the way. Guru Nanak teaches the path of the grihast, the householder: holiness is found by living an ordinary life well, not by escaping it. "Maa-oo pee-oo kirat gavaa-in tabar rovan Dhaahee" — they leave their parents' way of life, and their families cry out. That crying matters. Walking away from love and duty is part of what makes that path wrong. The body and the world aren't enemies to punish. They're gifts to honor.
That's why the second half turns into a song about water and rain. "Vuthai ho-i-ai ho-ay bilaaval jee-aa jugat samaanee" — when it rains, there is joy; water is the key to life. Rain grows the corn, the sugarcane and the cotton for our clothes. It gives the cows grass, and their milk becomes butter and ghee for feasts and worship. Guru Nanak shows the whole world full of blessing. Rain, growth, food: it's the One's kindness you can see. Turning away from water to be holy means turning away from one of grace's clearest faces.
Then comes the real subject. "Guroo samund nadee sabh sikhee naatai jit vadi-aa-ee" — the Guru is the ocean, all the teachings are rivers; bathing there brings true greatness. This is the real bath. Not a ritual bath, and not the outer washing other verses call useless, but the heart washed in the Guru's ocean. Think of jumping into a clean lake on a hot day and coming out fresh. The verse moves from a false holiness that runs from life, to the goodness of rain and ordinary living, to the true bathing place: the teaching itself.
A Question to Sit With
Where might 'holiness' tempt you toward fleeing or denying life, when the deeper path is to live it rightly and wash your heart in wisdom?
