Kṛṣṇa, the Supreme Personality of Godhead, does not require any education, but He gives a chance to the goddess of learning to serve Him. Being self-sufficient, Kṛṣṇa does not require the service of any living entity, although He has many devotees. It is because Kṛṣṇa is so kind and merciful that He gives the opportunity to everyone to serve Him, as though He requires the service of His devotees.
Regarding His moral principles, it is stated in the Śrīmad-Bhāgavatam that Kṛṣṇa is ruling over Vṛndāvana as death personified to the thieves, as pleasing bliss to the pious, as the most beautiful Cupid to the young girls and as the most munificent personality to the poor men. He is as refreshing as the full moon to His friends, and to His opponents He is the annihilating fire generated from Lord Śiva. Kṛṣṇa is therefore the most perfect moralist in His reciprocal dealings with different kinds of persons. When He is death personified to the thieves, it is not that He is without moral principles or that He is cruel; He is still kind, because to punish thieves with death is to exhibit the highest quality of moral principles. In the Bhagavad-gītā, also, Kṛṣṇa says that He deals with different kinds of persons according to their dealings with Him. Kṛṣṇa's dealings with devotees and with nondevotees, although different, are both equally good. Because Kṛṣṇa is all good, His dealings with everyone are always good.
12. Highly Intelligent A man is called intelligent if he has a sharp memory and fine discretion. As far as Kṛṣṇa's memory is concerned, it is said that when He was studying in the school of Sāndīpani Muni in Avantīpur, He showed such a sharp memory that by once taking instructions from the teacher He immediately became perfect in any subject. Actually, His going to the school of Sāndīpani Muni was to show the people of the world that however great or ingenious one may be, he must go to higher authorities for general education. However great one may be, he must accept a teacher or spiritual master.
