Maharaja Rsabha, son of King Nabhi and Merudevi, is a Supreme Avatar. He taught his sons how to follow the path of perfection by practicing obedience or submission, purifying our existence and leading us to spiritual happiness, eternal and ever-growing. Everyone seeks happiness, but no one knows where to find eternal happiness, infinite happiness. Fools seek to replace this real happiness with the pleasure of the senses, forgetting that this material happiness is also within the reach of dogs and pigs. No animal of any kind is deprived of sensual pleasures; all, on the contrary, including humans, can obtain them in abundance. The human form, however, is not made for so cheap a happiness; Man is made to know the eternal and infinite happiness of spiritual realization, attained by obedience or submission, voluntarily accepting to follow the path of asceticism and abstention from material pleasures. Those who have been trained to abstain from all material pleasure are not troubled by the senses. They can take the path of renunciation and gradually take steps to attain the level of master scholar respected by all groups of society. King Rsabha therefore propagated these teachings, and he himself, in the end, detached himself completely from all bodily needs. Such detachment is very rare, and must not be imitated artificially by fools, but rather admired by all.
The next Supreme Avatar, who appeared at the prayer of the wise, was King Prthu. He cultivated the soil to produce various commodities, thus making the earth beautiful and attractive.
At the advent of Prthu Maharaja, the Earth was in the most complete chaos because of the bad government and the corrupt life of the king, his father. In the face of disaster, the learned sages and masters, who form the thinking elite of society, not only begged the Lord to descend to earth, but dethroned the impious king. It is the duty of a king to be virtuous and to look after the good of all citizens. If he neglects his duty, the group of thinkers, intellectuals, must dethrone him. They themselves, however, never occupy the throne, for they have far more important duties to fulfill for the good of all. Rather than occupying the throne, wise and learned teachers begged the Lord to appear, and so came Maharaja Prthu. True sages or true learned scholars never aspire to political office.
Prthu Maharaja made the soil productive, and so not only were the citizens happy to have such a good king, but the Earth itself became beautiful and attractive to everyone.
When the total flood (flood) occurred after the Caksusa Manu era, and the whole world was deeply submerged by the waters, the Lord appeared in the form of a fish and protected the Vaivasvata Manu by placing it on a vessel.
Such devastation does not necessarily occur at the end of each Manu era; and the one evoked by our verse was then produced only to show the marvel to the faithful Satyavrata. The wise Jiva Gosvami has definitively proven, with the support of authoritative writings in the field-Visnu-dharmottara, Markandeya Purana,
