This incarnation of Lord Buddha is not the same Buddha incarnation we have in the present history of mankind. According to Śrīla Jīva Gosvāmī, the Buddha incarnation mentioned in this verse appeared in a different Kali age. In the duration of life of one Manu there are more than seventy-two Kali-yugas, and in one of them the particular type of Buddha mentioned here would appear. Lord Buddha incarnates at a time when the people are most materialistic and preaches commonsense religious principles. Such ahiṁsā is not a religious principle itself, but it is an important quality for persons who are actually religious. It is a commonsense religion because one is advised to do no harm to any other animal or living being because such harmful actions are equally harmful to he who does the harm. But before learning these principles of nonviolence one has to learn two other principles, namely to be humble and to be prideless. Unless one is humble and prideless, one cannot be harmless and nonviolent. And after being nonviolent one has to learn tolerance and simplicity of living. One must offer respects to the great religious preachers and spiritual leaders and also train the senses for controlled action, learning to be unattached to family and home, and enacting devotional service to the Lord, etc. At the ultimate stage one has to accept the Lord and become His devotee; otherwise there is no religion. In religious principles there must be God in the center; otherwise simple moral instructions are merely subreligious principles, generally known as upadharma, or nearness to religious principles.
