Once, when the Padavas were in exile, the great sage Durvasa visited the palace of Duryodhan, where he was served very nicely by the Kaurava Prince and his numerous brothers. They satisfied the great ascetic and thousands of his disciples by receiving them very nicely and feeding them delicious, sumptuous food. Being very pleased with Duryodhana, Durvasa rishi told him to ask for a boon. After carefully considering and discussing with his uncle Shakuni and other brothers, he asked Durvasa rishi to go visit the Pandavas in the forest in the afternoon and bless them. Hearing this, the great sage was pleased to see that Duryodhan wanted his brothers, the pandavas, to be blessed by the sage and had therefore asked him to go visit them, and being thus pleased, he said that he would certainly go visit the Pandavas. However, in truth, the reason behind his this request was something quite different. Duryodhan and his wicked associates had concluded that since Durvasa Rishi was going to go there with thousands of his disciples and that too in the afternoon, the Pandavas would not be able to serve them prasad, because, even though Draupadi had an akshaya patra, or a pot that could feed unlimited number of people without the contents reducing in the least, once she had eaten, nothing would remain, and in the afternoon she would certainly have eaten by the time the sage would go there. Thus, when the sage will see that they are not serving him nicely, he, famous as he was for getting angry very fast, would curse them. Thinking in this way, he smirked and thought about the misfortune that was about to befall the Pandavas.
Fulfilling the desire of Duryodhan, Durvasa rishi went to the place where Maharaj Yudhishthir was staying with his brothers and Draupadi, and seeing him approach, Yudhishthir offered him respectful obeisances. Durvasa rishi then informed him that he would go with his disciples to the near-by river for a bath and would then come to his hut for prasad and that he should make the necessary arrangements. Saying thus, he departed for the river, leaving behind a very worried Yudhishthir, who immediately went to the hut and asked Draupadi if she had already eaten. Replying that she had eaten and seeing the worry on the face of Yudhishthir, she enquired about the reason. He then informed her and his brothers about the arrival of the great sage Durvasa and that he would very soon be coming to take prasad with thousands of his disciples. Knowing the angry nature of the sage, all of them became extremely concerned. Knowing no other shelter but Sri Krishna, Draupadi immediately remembered him and called out for him. Being called by his dear devotee, Krishna immediately appeared there and asked them the cause of their anxiety. Upon being informed about the imminent arrival of Durvasa rishi and his disciples, Krishna asked Draupadi to bring him the pot and saw that a small piece of rice was stuck to it. Taking that small morsel of rice and some water, Krishna felt completely satiated and burped with satisfaction. Being the soul of the entire universe, his satisfaction meant the satisfaction of one and all, and therefore, all the sages taking their bath in the river also became completely satisfied. Thinking that Draupadi would have prepared prasad for them and that they would not be able to accept it because of being full, they all decided to leave the place without going to the hut of the Pandavas. And thus, Durvasa rishi left the place along with his disciples and went elsewhere. When Yudhishthir sent one of his brothers to go to the sages, they got to know that the sages had already left, and they thus felt relieved. They all felt extremely grateful to Krishna for saving them from yet another difficult situation.
This pastime practically demonstrates how Krishna is the root of everything and how by satisfying Krishna, everyone else is automatically satisfied. Just like one must water the root of the tree rather than watering every individual leaf and branch; and one must feed the stomach rather than feeding each limb, similarly, one must only serve Sri Krishna, and all others obligations shall automatically be fulfilled. Therefore, all our endeavours should be aimed at satisfying the Supreme Personality of Godhead, Sri Krishna, and by doing so, all others will automatically be satisfied.
