Real Power
All of us are familiar with the saying 'Knowledge is power' but are not aware of a systematic process to convert knowledge into power. Real power comes from a person's awareness of subtle details and specialized knowledge and applying the specialized knowledge and specialized skills to manipulate events, circumstances and things to the person's advantage. The person with the most real power is often not the person with the highest office or position. A person who has real power does not show it, unless the situation really demands it and there is no other alternative. Only an insecure person who lacks real power has a need to constantly remind others that he is powerful.
In the Mahabharata, there are several gods who appear as characters - including the devas such as Indra, Surya etc as well as the gods of the holy trinity like Shiva. Indra has the title of the king of the gods, and Shiva has the title of 'Mahadeva' or the greatest of the gods. The central character of the Mahabharata however is Vishnu, or Krishna, who does not have any great title as such. He is merely a preserver, not a creator or destroyer. Krishna seems like an ordinary person to others in most situations except for certain specific events where he has no choice but to display his power to protect innocent people. There is an instance where Indra gets angry and spiteful with the people of Gokul and sends a fierce storm to the village. However Krishna protects the people by holding the mighty mountain Govardhana on his little finger. After the event, he diverts people's attention from this stupendous feat by asking them to worship the mountain Govardhana which protected them.
In another instance in the Mahabharata, Jayadratha's undergoes penance to please Shiva and seek a boon to defeat the Pandavas. Lord Shiva grants him a boon to hold the Pandavas (other than Arjuna) for one day in battle. This boon directly leads to Abhimanyu's death in a very unfair and cruel manner. This shows that Shiva is powerless to refuse to grant a boon even to an evil person who seeks to please Shiva only with a selfish and evil motive of revenge, even if it leads to a consequence such as the killing of an innocent and brave lad by a group of warriors even while he is unarmed. The real power is with Krishna, who is able to manipulate great warriors like Bhishma, Drona and Karna to their death by strategies based on specialized knowledge about their personalities including their strengths and weaknesses. He does not have to wield any weapons to achieve his objective.
