After the journey of Multan, Baba Nanak again turned towards Kartarpur.
His impact increased by leaps and bounds and he made people of kaliyug remember Nam.
Desiring anything except the Nam of the Lord, is invitation to multiplying sufferings.
In the world, he established the authority (of his doctrines) and started a religion, devoid of any impurity (niramal panth).
During his life time he waved the canopy of Guru seat on the head of Lahina(Guru Angad) and merged his own light into him.
Guru Nanak now transformed himself.
This mystery is incomprehensible for anybody that awe-inspiring (Nanak) accomplished a wonderful task.
He converted (his body) into a new form.
