Lord Ganesh, who is also known by various other names such as Ganapathi, Vinaayaka or Vighneswara, is the God who helps us overcome obstacles in life. He is the son of Lord Shiva and Mother Parvathi. Every rite or ceremony or project starts with the worship of Lord Ganesha.
Ganesh is the lord of new beginnings and guardian of entrances. A prayer to Ganesh is invariably accompanied by smashing a coconut, symbolic of smashing the undesirable forces inherent in oneself.
. The coconut is broken and placed before the Lord. It is later distributed as prasaada.
The fibre covering of the dried coconut is removed except for a tuft on the top. The marks on the coconut make it look like the head of a human being. The coconut is broken, symbolising the breaking of the ego. The juice within, representing the inner tendencies (vaasanas) is offered along with the white kernel - the mind, to the Lord.
A mind thus purified by the touch of the Lord is used as prasaada.
The marks on the coconut are even thought to represent the three-eyed Lord Shiva and therefore it is considered to be a means to fulfill our desires
