The brunt of Kalu's biting tongue had to be borne mostly by his comely wife, Tripta. Daughter of one Rama of Chaliawala in the Majha country situated between the rivers Ravi and Beas, she was a complete contrast to her husband and was "gifted with a sympathetic, generous nature, mild and gentle and extremely soft- spoken". She was devoted to her husband in spite of his faults and "patiently put up with his outbursts of temper and made a point of never crossing him in any way." It was this attitude of self-abnegation and self-effacement of the mild-mannered Tripta that ensured, more or less, a smooth domestic life, though occasional quarrels continued taking place.
In 1464, Mehta Kalu and Tripta were blessed with a daughter, who was born in the house of her maternal grand-parents which was a common practice and hence was named, Nanaki. The birth of a daughter is said to have disappointed Kalu who became even more rude in his dealings with his wife. Therefore, like typical Hindu women of the age, Tripta started following strict religious regimens so that the Gods may be pleased and bless her with a son. The Gods granted her wish and after five long years, on the third day of the light half of the month of Baisakh, of A.D. 1469, was born her illustrious son, Guru Nanak.
