The purport of this expression by Vasudeva is this: although he had eight sons born in the womb of Devakī, unfortunately they were all gone. He could not even keep his one son Kṛṣṇa with him. Vasudeva was feeling His separation, but he could not express the real fact. "Please tell me about the welfare of Vṛndāvana," he said. "You have many animals—are they happy? Are they getting sufficient grass and water? Please also let me know whether the place where you are now living is undisturbed and peaceful." This inquiry was made by Vasudeva because he was very anxious about Kṛṣṇa's safety. He knew that Kaṁsa and his followers were trying to kill Kṛṣṇa by sending various kinds of demons. They had already resolved that all children born within ten days of the birthday of Kṛṣṇa should be killed. Because Vasudeva was so anxious about Kṛṣṇa, he inquired about the safety of His residence. He also inquired about Balarāma and His mother, Rohiṇī, who were entrusted to the care of Nanda Mahārāja. Vasudeva also reminded Nanda Mahārāja that Balarāma did not know His real father. "He knows you as His father. And now you have another child, Kṛṣṇa, and I think you are taking very nice care of both of Them." It is also significant that Vasudeva inquired about the welfare of Nanda Mahārāja's animals. The animals, and especially the cows, were protected exactly in the manner of one's children. Vasudeva was a kṣatriya, and Nanda Mahārāja was a vaiśya. It is the duty of the kṣatriyas to give protection to the citizens, and it is the duty of the vaiśyas to give protection to the cows. The cows are as important as the citizens. Just as the human citizens should be given all kinds of protection, so the cows also should be given full protection.
Vasudeva continued to say that the maintenance of religious principles, economic development and the satisfactory execution of meeting the demands of the senses depend on cooperation among relatives, nations and all humanity. Therefore, it is everyone's duty to see that his fellow citizens and the cows are not put into difficulty. One should see to the peace and comfort of his fellow man and the animals. The development of religious principles, economic development and sense gratification can then be achieved without difficulty. Vasudeva expressed his sorrow due to not being able to give protection to his own sons born of Devakī. He was thinking that religious principles, economic development and the satisfaction of his senses were therefore all lost.
