The Wisdom of the Heavens has it, That a horoscope is only powerful, If the luminaries are strong, That is, the Sun and the Moon ! They are political planets, Not Planets but Luminaries Sun is the KIng and Moon is Queen, In the Government of the Almighty ! Bhanu Shambhu Udeeritho Himakaro, Durga Balonyasay cheth Kalyada Kuja Gascha Rasi Dharanee Putra Sutha Shanmugha ! So it is only natural, That KIng Sun got portfolio of King SIva And Queen Moon, Queen Parvathy In Anthropomorphisation of Planets !
Muruga, as he was a martial arts expert, Became the Martial Commander, He was well coached by Parvathy, Who gave him the mighty Vel ( spear ) As hindrances block all endeavors, Remover of such became Ganesh. His great brain saves devotees, From major impediments !
As Mercury represents Knowledge Academic, Which is weapon mightiest, Incarnate Vishnu was assigned to him, Sree Rama Adyavatara VIshnur Udita ! The fastest moving planet is Jove, And the greatest benefactor, 1300 Earths can be fit into Jove, Brihatam tasya esha Patih iti Brihaspati. Knowledge, both worldly and divine, Is the prerogative of Jupiter ! So the mighty Lord Vishnu was assigned, Soumyotha Vishnur Guru Prosperity is controlled by Venus, So Lakshmi was assigned to him Annapoorneswari Lakshmi, Durga va Bhrigu Nandana. While Bhagavati was assigned to Venus Ayyappa / Hanuman became Saturn's Deity ! Shukra syath Gana nayako Bhagavatee, Mandasthu Sasta maya !
