In the Bhagavad-gītā we can see that Arjuna desired not to fight with his brothers and relations just to satisfy his own personal desires. But when he heard the message of the Lord, Śrīmad Bhagavad-gītā, he changed his decision and served the Lord. And for his doing so, he became a famous devotee of the Lord, for it is declared in all the scriptures that Arjuna attained spiritual perfection by devotional service to the Lord in friendship.
The fighting was there, the friendship was there, Arjuna was there, and Kṛṣṇa was there, but Arjuna became a different person by devotional service. Therefore, the prayers of Kuntī also indicate the same categorical changes in activities. Śrīmatī Kuntī wanted to serve the Lord without diversion, and that was her prayer. This unalloyed devotion is the ultimate goal of life. Our attention is usually diverted to the service of something which is nongodly or not in the program of the Lord. When the program is changed into the service of the Lord, that is to say when the senses are purified in relation with the service of the Lord, it is called pure unalloyed devotional service.
