Kṛṣṇa is beautiful at His different ages—namely, His childhood, His boyhood and His youth. Out of these three, His youth is the reservoir of all pleasures and is the time when the highest varieties of devotional service are acceptable. At that age, Kṛṣṇa is full with all transcendental qualities and is engaged in His transcendental pastimes. Therefore, devotees have accepted the beginning of His youth as the most attractive feature in ecstatic love.
At this age Kṛṣṇa is described as follows: "The force of Kṛṣṇa's youth was combined with His beautiful smile, which defeated even the beauty of the full moon. He was always nicely dressed, in beauty surpassing even Cupid, and He was always attracting the minds of the gopīs, who were thereby always feeling pleasure."
7. Wonderful Linguist
Rūpa Gosvāmī says that a person who knows the languages of different countries, especially the Sanskrit language, which is spoken in the cities of the demigods—as well as other worldly languages, including those of the animals—is called a wonderful linguist. It appears from this statement that Kṛṣṇa can also speak and understand the languages of the animals. An old woman in Vṛndāvana, present at the time of Kṛṣṇa's pastimes, once stated in surprise: "How wonderful it is that Kṛṣṇa, who owns the hearts of all the young girls of Brajabhūmi, can nicely speak the language of Brajabhūmi with the gopīs, while in Sanskrit He speaks with the demigods, and in the language of the animals He can even speak with the cows and buffalo! Similarly, in the language of the Kashmere Province, and with the parrots and other birds, as well as in most common languages, Kṛṣṇa is so expressive!" She inquired from the gopīs as to how Kṛṣṇa had become so expert in speaking so many different types of languages.
A person whose word of honor is never broken is called truthful. Kṛṣṇa once promised Kuntī, the mother of the Pāṇḍavas, that He would bring her five sons back from the battlefield of Kurukṣetra. After the battle was finished, when all the Pāṇḍavas had come home, Kuntī praised Kṛṣṇa because His promise was so nicely fulfilled. She said, "Even the sunshine may one day become cool and the moonshine may one day become hot, but still Your promise will not fail. Similarly, when Kṛṣṇa, along with Bhīma and Arjuna, went to challenge Jarāsandha, He plainly told Jarāsandha that He was the eternal Kṛṣṇa, present along with two of the Pāṇḍavas. The story is that both Kṛṣṇa and the Pāṇḍavas—in this case Bhīma and Arjuna—were kṣatriyas (warrior-kings). Jarāsandha was also a kṣatriya and was very charitable toward the brāhmaṇas. Thus Kṛṣṇa, who had planned to fight with Jarāsandha, went to him with Bhīma and Arjuna in the dress of brāhmaṇas. Jarāsandha, being very charitable toward the brāhmaṇas, asked them what they wanted, and they expressed their desire to fight with him. Then Kṛṣṇa, dressed as a brāhmaṇa, declared Himself to be the same Kṛṣṇa who was the King's eternal enemy.
9. Pleasing Talker
A person who can speak sweetly even with his enemy just to pacify him is called a pleasing talker. Kṛṣṇa was such a pleasing talker that after defeating His enemy, Kāliya, in the water of Yamunā, He said: "My dear King of the snakes, although I have given you so much pain, please do not be dissatisfied with Me. It is My duty to protect these cows, which are worshiped even by the demigods. Only in order to save them from the danger of your presence have I been obliged to banish you from this place."
Kāliya was residing within the water of the Yamunā, and as a result the back portion of that river had become poisoned. Thus so many cows who had drunk the water had died. Therefore Kṛṣṇa, even though He was only four or five years old, dipped Himself into the water, punished Kāliya very severely and then asked him to leave the place and go elsewhere.
Kṛṣṇa said at that time that the cows are worshiped even by the demigods, and He practically demonstrated how to protect the cows. At least people who are in Kṛṣṇa consciousness should follow in His footsteps and give all protection to the cows. Cows are worshiped not only by the demigods. Kṛṣṇa Himself worshiped the cows on several occasions, especially on the days of Gopāṣṭamī and Govardhana Pūjā.
10. Fluent in All Languages
A person who can speak meaningful words and with all politeness and good qualities is called vāvadūka, or fluent. There is a nice statement in the Śrīmad-Bhāgavatam regarding Kṛṣṇa's speaking politely. When Kṛṣṇa politely bade His father, Nanda Mahārāj, to stop the ritualistic offering of sacrifice to the raingod, Indra, a wife of one village cowherd man became captivated. She later thus described the speaking of Kṛṣṇa to her friends: "Kṛṣṇa was speaking to His father so politely and gently that it was as if He were pouring nectar into the ears of all present there. After hearing such sweet words from Kṛṣṇa, who will not be attracted to Him?"
Kṛṣṇa's speech, which contains all good qualities in the universe, is described in the following statement by Uddhava: "The words of Kṛṣṇa are so attractive that they can immediately change the heart of even His opponent. His words can immediately solve all of the questions and problems of the world. Although He does not speak very long, each and every word from His mouth contains volumes of meaning. These speeches of Kṛṣṇa are very pleasing to my heart."
