If God is Great, He must be most expert in all activities.
1. Immense physical strength: A person who has extraordinary bodily strength is called baliyan. 
When Krishna killed Aristasura, some of the gopis said, “My dear friends, just see how Krishna has killed Aristasura! Although he was stronger than a mountain, Krishna plucked him up just like a piece of cotton and threw him away without any difficulty!” At the age of seven, Krishna lifted the Govardhana Hill on the little finger of His left hand and thus protected all the Vrajavasis from Indra’s wrath. – Nectar of Devotion, Chapter 21
2. Powerful wrestler: Krishna and Canura and then Balarama and Mustika locked themselves hand to hand, leg to leg, and each began to press against the other with a view to coming out victorious. They joined palm to palm, calf to calf, head to head, chest to chest and began to strike each other. The fighting increased as they pushed each other from one place to another. One captured the other and threw him down on the ground, and another rushed from the back to the front of another and tried to overcome him with a hold. The fighting increased step by step. There was picking up, dragging and pushing, and then the legs and hands were locked together. All the arts of wrestling were perfectly exhibited by the parties as each tried his best to defeat his opponent. – Krishna Book, Chapter 44
3. Expert linguist: An old woman in Vrindavana, present at the time of Krishna’s pastimes, once stated in surprise, “How wonderful it is that Krishna, who owns the hearts of all the young girls of Vrajabhumi, can nicely speak the language of Vrajabhumi with the gopis, 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 Kashmir Province, and with the parrots and other birds, as well as in most common languages, Krishna is so expressive!” – Nectar of Devotion, Chapter 21
4. Expert cowherd boy: One of the gopis told Mother Yashoda, “My dear mother, your son is very expert among the cowherd boys. He knows all the different arts of how to tend the cows and how to play the flute.” Krishna had many thousands of cows, and they were divided into groups according to their colors. They were also differently named according to color. When He would prepare to return from the pasturing ground, He would gather all the cows. As Vaishnavas count 108 beads, which represent the 108 individual gopis, so Krishna would also count on 108 beads to count the different groups of cows.- Krishna Book, Chapter 35
5. Fluent: Krishna’s speech, which contains all good qualities in the universe, is described in the following statement by Uddhava: “The words of Krishna 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 Krishna are very pleasing to my heart.” – Nectar of Devotion, Chapter 21
6. Highly learned: After hearing only once from Their teacher, Krishna and Balarama learned all the arts and sciences. In sixty-four days and sixty-four nights, They learned all the necessary arts and sciences required in human society. During the daytime They took lessons on a subject from the teacher, and by nightfall They were expert in that department of knowledge. – Krishna Book, Chapter 45
7. Super-intelligent: Krishna’s fine discretion was exhibited when He was fighting with the untouchable king who attacked the city of Mathura. According to Vedic rites, those who are untouchable are not to be touched by the kshatriya kings, not even for killing. Therefore, when the untouchable king seized the city of Mathura, Krishna did not think it wise to kill him directly with His own hand. Still the king had to be killed, and therefore Krishna decided with fine discretion that He should flee from the battlefield so that the untouchable king would chase Him. He could then lead the king to the mountain where Muchukunda was lying asleep. Muchukunda had received a benediction from Karttikeya to the effect that when he awoke from his sleep, whomever he might see would at once be burnt to ashes. Therefore Krishna thought it wise to lead the untouchable king to that cave, so that the king’s presence would awaken Muchukunda and he would at once be burnt to ashes. – Nectar of Devotion, Chapter 21
8.Artistic: One who can talk and dress himself very artistically is called vidagdha. This exemplary characteristic was visible in the personality of Sri Krishna. It is spoken of by Radharani as follows: “My dear friend, just see how Krishna has nicely composed songs and how He dances and speaks funny words and plays on His flute, wearing such nice garlands. He has dressed Himself in such an enchanting way, as though He had defeated all kinds of players at the chessboard. He lives wonderfully at the topmost height of artistic craftsmanship.” – Nectar of Devotion, Chapter 21 
9. Expert flute player: Krishna was very expert in playing the flute, and the gopis were captivated by the sound vibration, which was attractive not only to them but to all living creatures who heard it. One of the gopis told her friends, “The highest perfection of the eyes is to see Krishna and Balarama entering the forest and playing Their flutes and tending the cows with Their friends.” – Krishna Book, Chapter 21
10. Best teacher: One will find in the Bhagavad-gita all that is contained in other scriptures, but the reader will also find things which are not to be found elsewhere. That is the specific standard of the Gita. It is the perfect theistic science because it is directly spoken by the Supreme Personality of Godhead, Lord Sri Krishna. – Bhagavad-gita 1.1, purport
11. Wonderful dancer: As the gopis and Krishna danced together, a very blissful musical sound was produced from the tinkling of their bells, ornaments and bangles. It appeared that Krishna was a greenish sapphire locket in the midst of a golden necklace decorated with valuable stones. While Krishna and the gopis danced, they displayed extraordinary bodily features. The movements of their legs, their placing their hands on one another, the movements of their eyebrows, their smiling, the movements of the gopis’ breasts, clothes and earrings, their cheeks, their hair with flowers-as Krishna and the gopis sang and danced these combined to appear like clouds, thunder, snow and lightning. Krishna’s bodily features appeared just like a group of clouds, the gopis’ songs were like thunder, their beauty appeared to be just like lightning in the sky, and the drops of perspiration visible on their faces appeared like falling snow. In this way, the gopis and Krishna fully engaged in dancing. – Krishna Book, Chapter 33
12. Great warrior: He took His arrows from their quiver, and one after another He set them on the bowstring and shot them toward the enemy. They were so accurate that the elephants, horses and infantry soldiers of Jarasandha were quickly killed. The incessant arrows shot by Krishna appeared like a whirlwind of blazing fire killing all the military strength of Jarasandha. As Krishna released His arrows, all the elephants gradually began to fall, their heads severed by the arrows. Similarly, all the horses fell, their necks severed, and the chariots fell also, along with their flags and the fighters and drivers on the chariots. Almost all the infantry soldiers fell on the field of battle, their heads, hands and legs cut off. – Krishna Book, Chapter 50
13. Infallible charioteer: Although Lord Krishna is the Supreme Personality of Godhead, out of His causeless mercy He was engaged in the service of His friend. He never fails in His affection for His devotees, and thus He is addressed herein as infallible. As charioteer, He had to carry out the orders of Arjuna, and since He did not hesitate to do so, He is addressed as infallible. Although He had accepted the position of a charioteer for His devotee, His supreme position was not challenged. – Bhagavad-gita 1.21-22, purport
