Ambarisha

Ambarisha (Sanskrit: अम्बरीषः, Ambarīṣa), in Hindu mythology, was an Ikshvaku king and son of Nabhaga. According to the Bhagavata Purana, he was a great devotee of Vishnu and adhered firmly to the truth. He performed a yaga with such great devotional fervour that Lord Narayana was pleased to bless him with Sudarshana Chakra (Sudarshana meaning "good vision") and which manifested as a wheel of prosperity, peace and security to his kingdom. Once, Ambarisha performed the Dvadasi Vratha, which required that the king must start a fast on Ekadashi and break it at the start of Dvadasi and feed all the people. As the moment of breaking the fast was drawing near, the mighty sage Durvasa arrived and was received with all honours by Ambarisha. Durvasa agreed to the king's request to be his honoured guest, and asked the king to wait until he finished his bath in the river and returned. As the auspicious moment approached when the king had to break his fast to fulfil the vow of the vrata, Durvasa did not turn up. On the advice of the sage Vasishta, the king broke his fast by taking a Tulasi leaf with water, and waited for the arrival of sage Durvasa to offer him food.
