1) Birth lagna is Taurus and Venus is its lord. Exalted moon (47*45’) is very near birth lagna (50*41’). Vrushabha lagne Chandra stithau, su-roopam; paripoorna bhagyadaha = Moon bestows him handsome and strong ,body and the period of Moon is highly beneficial to him. 2) Saturn’s (yoga-kaaraka for Taurus) drushti (aspect) is on Moon and birth lagna; so Sri Krishna is very handsome. Venus, Moon, Mars and Saturn have dominant influence and this combined beneficial effect has given Sri Krishna a very graceful and handsome appearance.
3) Venus is in his own house (5th from Lagna) in Nava amsa chart; this bestowed him magnanimous nature: he was epitome of courtesy and kindness even to poor person like Kuchela; and to low born Chandala and servant-maid Kubja (as we find in Bhagavahta).
3) Mars is in cancer and is debilitated; and gave him neecha-bhange raja-yoga; Mars is martial nature planet; he has Varga-uttama-amsa; this gave Sri Kriushna invincible martial powers; Mars in 3rd house (courage & bravery). He fought bravely and killed hundreds of mighty raakshasas like Kamsa, Sisupala, Dantavakra. His tact, courage, resourcefulness in battle field are extolled several times in Sri Bhagavatha. He caused death of Kaalnemi like raakshasaas by tact, because they can not be killed in face-to-face fight by the boons they acquired.
All these super-yogas made him a Ruler of the world and an Emperor of the Universe.
