Out of the 10 avatara, Krishnaavathaara is said to be the purnavathaaram. In worldly as well as in spiritual matters Lord Krishna's life and thoughts are unrivalled till today, & will be like that only forever. The Raasaleela is so unique, His yogic powers and vision as depicted in Mahaa Bhaagavatham & in Mahaa Bhaaratham are beyond imagination, displayal of viswaroopam & viraatroopam, spiritual wisdom as seen in the Gita, practical wisdom as projected in various occasions during the Kurukshetra war, His advice that the target (lakshyam) will justify the means (maargam) when it comes to a war which is a clash between dharma & adharma..... Here there are no comparisons. All His actions are sublime, each more inspiring than the other.

He advising Arjun to fight even his close relatives to establish dharma and justice . sadly now people overlook their loved one's fault and blame the other side . truth and justice knows no relationship
