Śukadeva Gosvāmī was very much encouraged when Mahārāja Parīkṣit asked him why the cowherd boys did not discuss the death of Aghāsura until after one year had passed. He explained thus: "My dear King, you are making the subject matter of the transcendental pastimes of Kṛṣṇa fresher by your inquisitiveness."
It is said that it is the nature of a devotee to constantly apply his mind, energy, words, ears, etc., in hearing and chanting about Kṛṣṇa. This is called Kṛṣṇa consciousness, and for one who is rapt in hearing and chanting about Kṛṣṇa, the subject matter never becomes hackneyed or old. That is the significance of transcendental subject matter in contrast to material subject matter. Material subject matter becomes stale, and one cannot hear a certain subject for a long time; he wants change. But as far as transcendental subject matter is concerned, it is called nitya-nava-navāyamāna. This means that one can go on chanting and hearing about the Lord and never feel tired but remain fresh and eager to hear more and more.
It is the duty of the spiritual master to disclose all confidential subject matter to the inquisitive and sincere disciple. Thus Śukadeva Gosvāmī began to explain why the killing of Aghāsura was not discussed until one year had passed. Śukadeva Gosvāmī told the King, “Now hear of this secret with attention. After saving His friends from the mouth of Aghāsura and killing the demon, Lord Kṛṣṇa brought His friends to the bank of the Yamunā and addressed them as follows: "My dear friends, just see how this spot is very nice for taking lunch and playing on the soft, sandy Yamunā bank. You can see how the lotus flowers in the water are beautifully blown and how they distribute their fragrance all around. The chirping of the birds along with the cooing of the peacocks, surrounded by the whispering of the leaves in the trees, combine and present sound vibrations that echo one another. And this just enriches the beautiful scenery created by the trees here. Let us have our lunch in this spot because it is already late and we are feeling hungry. Let the calves remain near us, and let them drink water from the Yamunā. While we engage in our lunch-taking, the calves may engage in eating the soft grasses that are in this spot."
On hearing this proposal from Kṛṣṇa, all the boys became very glad and said, "Certainly, let us all sit down here to take our lunch." They then let loose the calves to eat the soft grass. Sitting down on the ground and keeping Kṛṣṇa in the center, they began to open their lunch boxes brought from home. Lord Śrī Kṛṣṇa was seated in the center of the circle, and all the boys kept their faces toward Him. They ate and constantly enjoyed seeing the Lord face to face. Kṛṣṇa appeared to be the whorl of a lotus flower, and the boys surrounding Him appeared to be its different petals. The boys collected flowers, leaves of flowers and the bark of trees and placed their lunch on them, as well as in their boxes, and thus they began to eat their lunch, keeping company with Kṛṣṇa. While taking lunch, each boy began to manifest different kinds of relations with Kṛṣṇa, and they enjoyed each other's company with joking words. While Lord Kṛṣṇa was thus enjoying lunch with His friends, His flute was pushed within the belt of His cloth on His right side, and His bugle and cane were pushed in on the left-hand side of His cloth. In his left palm He was holding a lump of food prepared with yogurt, butter, rice and pieces of fruit salad, which could be seen through His petallike finger-joints. The Supreme Personality of Godhead, who accepts the results of all great sacrifices, was laughing and joking, enjoying lunch with His friends in Vṛndāvana. And thus the scene was being observed by the demigods from heaven. As for the boys, they were simply enjoying transcendental bliss in the company of the Supreme Personality of Godhead.
At that time, the calves that were pasturing nearby entered into the deep forest, allured by new grasses, and gradually went out of sight. When the boys saw that the calves were not nearby, they became afraid for their safety, and they immediately cried out, "Kṛṣṇa!" Kṛṣṇa is the killer of fear personified. Everyone is afraid of fear personified, but fear personified is afraid of Kṛṣṇa. By crying out the word "Kṛṣṇa," the boys at once transcended the fearful situation. Out of His great affection, Kṛṣṇa did not want His friends to give up their pleasing lunch engagement and go searching for the calves. He therefore said, "My dear friends, you need not interrupt your lunch. Go on enjoying. I am going personally to find the calves." Thus Lord Kṛṣṇa, still carrying the lump of yogurt-and-rice preparation in His left hand, immediately started to search out the calves in the caves and bushes. He searched in the mountain holes and in the forests, but nowhere could He find them.
