In this connection, Vidura, while trying to detach his elder brother, Dhṛtarāṣṭra, from his familial attachments, said, "My dear brother, you just fix your mind on the lotus feet of Kṛṣṇa, who is worshiped with beautiful erudite verses by great sages and saintly persons. Kṛṣṇa is the supreme deliverer amongst all other deliverers. Undoubtedly there are great demigods like Lord Śiva and Lord Brahmā, but their positions as deliverers depend always upon the mercy of Kṛṣṇa." Therefore Vidura advised his elder brother Dhṛtarāṣṭra to concentrate his mind and worship only Kṛṣṇa. If one simply chants the holy name of Kṛṣṇa, this holy name will rise within one's heart like the powerful sun and will immediately dissipate all the darkness of ignorance. Vidura advised Dhṛtarāṣṭra to therefore think always of Kṛṣṇa so that the volumes of contaminations due to sinful activities would be washed off immediately. In the Bhagavad-gītā (10.12) also Kṛṣṇa is addressed by Arjuna as paraṁ brahma paraṁ dhāma pavitram—the supreme pure. There are many other instances exhibiting Kṛṣṇa's supreme purity.
A person who can control his senses fully is called vaśī, or self-controlled. In this connection it is stated in the Śrīmad-Bhāgavatam: "All the 16,000 wives of Kṛṣṇa were so exquisitely beautiful that their smiling and shyness were able to captivate the minds of great demigods like Lord Śiva. But still they could not even agitate the mind of Kṛṣṇa, in spite of their attractive feminine behavior." Every one of the thousands of wives of Kṛṣṇa was thinking that Kṛṣṇa was captivated by her feminine beauty, but this was not the case. Kṛṣṇa is therefore the supreme controller of senses, and this is admitted in the Bhagavad-gītā, where He is addressed as Hṛṣīkeśa—the master of the senses.
A person who continues to work until his desired goal is achieved is called steadfast.
There was a fight between Kṛṣṇa and King Syamantaka, and Kṛṣṇa was to take a valuable jewel from the King. The King tried to hide himself in the forest, but Kṛṣṇa would not become discouraged. Kṛṣṇa finally got the jewel by seeking out the King with great steadfastness.
A person who tolerates all kinds of troubles, even though such troubles appear to be unbearable, is called forbearing.
When Kṛṣṇa was residing at the place of His spiritual master, He did not mind taking all troubles in rendering service to His guru, although His body was very soft and delicate. It is the duty of the disciple to execute all services unto the spiritual master, despite all kinds of difficulties. The disciple living at the residence of the spiritual master has to go begging from door to door and bring everything back to the spiritual master. When prasādam is being served, the spiritual master is supposed to call each and every disciple to come eat. If by chance the spiritual master forgets to call a disciple to partake of the prasādam, it is enjoined in the scriptures that the student should fast on that day rather than accept food on his own initiative. There are many such strictures. Sometimes, also, Kṛṣṇa went to the forest to collect dry wood for fuel.
