Shivling or Shiva lingam connects a devotee with the Supreme Being â“ Lord Shiva. The lingam is the symbol of Lord Shiva and the lingam puja helps the devotee in understanding Lord Shiva. The Lord cannot be described but still we say he is without a beginning and an end and is without a form. It is difficult for a devotee to understand this formless nature. Therefore Lord Shiva appeared in the form of Jyotirlinga before Brahma and Vishnu. The Lingam thus is a symbol of Lord Shiva. Each Lingam puja, step by step, takes the devotee to the eternal truth â“ that he/she is part of the Supreme Being.
Finally, ringing of bells or blowing of conch indicates the end of Puja. White ash (vibhuti) is rubbed on the forehead and it is also distributed. Fruits, sweets and coconut are distributed as â˜prasad.â™
Quoted:"After the panchamrit abhishek, the lingam is cleaned with water from Ganga. (This is might not be possible always so just normal water.) After this the lingam is smeared with sandalwood paste and is decked with flowers. Water and sandalwood paste is used to keep the lingam cool, as Lord Shiva is always in a highly inflammable state. In some Shiva temples, cooling liquid constantly drops from pot hung above the Lingam."
