The leaves, flowers and bark of Madar plants are hugely cherished by gods, but a Madar plant is strangely not offered like other plants. It is debarred and reprobated as a pain-giver. Perhaps the abuse of its making could not be endured by Lord Shiva, the supreme among Lords, and he embraced it with much love.
Generally Madar plants, with purple coloured flowers, are available everywhere and this kind of plant is utilised for medicinal purposes. But Madar plant, bearing white flowers is extremely rare. It is called white Madar (Shwetark). A person, who finds this type of Madar, becomes the focus of adoration of Lord Shiva and Ganesh. Numerous great scriptures and mythological stories speak about buried treasures definitely lying there or nearby, where the white Madar plant grows. Poverty departs from the house where its roots survive. Thus this plant ushers in affluence. It is the protector and makes Immortals have mercy upon humankind.
Therefore, the first task one should perform is to discover roots of a white Madar plant. Lord Ganesh lives in its root. Sometimes this root is available in the form of Lord Ganesh. Hence this root should be venerated with immense faith, assuming that it is the idol of Lord Ganesh. Vermilion should be smeared all over it. It needs to be wrapped in red cloth and set in the place where one worships other divinities.
Much has been written in its praise in umpteen great books. In brief, poverty, interference in growth, squabbles, disorder, curse, malevolent effect of evil spirits or sorcery are obliterated in the house where the Shwetaark Ganpati subsists. Therefore man should worship Lord Ganesh by reciting the following Mantra -
"Chatur Bhujam Raktatanum,
Trinetram, Pashaankushau Modak Paatra Dantau.
Parairdadhanam Saraseeruh Hastam,
Ganaa Dhinaatham Shashi Choodrneede. "
"Om Vakratrundaya Hum
Om Shree Ganeshaya Namah."
During puja or worship of Shwetark Ganesh, the worshipper should use red cloth, red flowers, rose wood and green grass. During japa, the worshipper should utilise coral mala or rudraksha mala; gur and gram flour should also be offered to the Shwetark Ganesh.
