Kṛṣṇa asked His father, "My dear father, what is this arrangement going on for a great sacrifice? What is the result of such a sacrifice, and for whom is it meant? How is it performed? Will you kindly let Me know? I am very eager to know this procedure, so please explain to Me the purpose of this sacrifice." Upon this inquiry, His father, Nanda Mahārāja, remained silent, thinking that his young boy would not be able to understand the intricacies of performing the yajña. Kṛṣṇa, however, persisted: "My dear father, for those who are liberal and saintly, there is no secrecy. They do not think anyone to be a friend, an enemy or a neutral party, because they are always open to everyone. And even for those who are not so liberal, nothing should be kept secret from the family members and friends, although secrecy may be maintained for persons who are inimical. Therefore you cannot keep any secrets from Me. All persons are engaged in fruitive activities. Some know what these activities are, and they know the result, and some execute activities without knowing the purpose or the result. A person who acts with full knowledge gets the full result; one who acts without knowledge does not get such a perfect result. Therefore, please let Me know the purpose of the sacrifice you are going to perform. Is it according to Vedic injunction? Or is it simply a popular ceremony? Kindly let Me know in detail about the sacrifice."
On hearing this inquiry from Kṛṣṇa, Mahārāja Nanda replied, "My dear boy, this ceremonial performance is more or less traditional. Because rainfall is due to the mercy of King Indra and the clouds are his representatives, and because water is so important for our living, we must show some gratitude to the controller of this rainfall, Mahārāja Indra. We are arranging, therefore, to pacify King Indra, because he has very kindly sent us clouds to pour down a sufficient quantity of rain for successful agricultural activities. Water is very important: without rainfall we cannot farm or produce grain, and without grain we cannot live. Therefore rain is necessary for successful religious ceremonies, economic development and, ultimately, liberation. So we should not give up this traditional ceremonial function; if one gives it up, being influenced by lust, greed or fear, then it does not look very good for him."
