The defenseless creatures, according to Śrīmad-Bhāgavatam, are the cows, brāhmaṇas, women, children and old men. Of these five, the brāhmaṇas and cows are especially mentioned in this verse because the Lord is always anxious about the benefit of the brāhmaṇas and the cows and is prayed to in this way. Therefore the Lord especially instructs that no one should be envious of these five, especially the cows and brāhmaṇas. In some of the Bhāgavatam readings, the word duhitṝḥ is used instead of duhatīḥ. But in either case, the meaning is the same. Duhatīḥ means “cow,” and duhitṝḥ can also be used to mean “cow” because the cow is supposed to be the daughter of the sun-god. Just as children are taken care of by the parents, women as a class should be taken care of by the father, husband or grown-up son. Those who are helpless must be taken care of by their respective guardians; otherwise the guardians will be subjected to the punishment of Yamarāja, who is appointed by the Lord to supervise the activities of sinful living creatures. The assistants, or messengers, of Yamarāja are likened here to vultures, and those who do not execute their respective duties in protecting their wards are compared to serpents. Vultures deal very seriously with serpents, and similarly the messengers will deal very seriously with neglectful guardians.
