Shiv Linga

what is Shivalinga? and
since how long /old it is in centre stages of majority of HINDU TEMPLES ?

Shivlinga symbolizes the generative principle of existence and is fused with Parvatiyoni, symbolizing the reproductive principle of existence - together, they symbolize the dual cohabitation within existence that manifests the multiplicity of life’s expressions.

thanks , is it represent reproductive organ of Shiva ? ,


I think it would be misleading if we restrict the symbol of Shivling to the reproductive organ of Shiva as in the reproductive organ of man. Everything that comes to us through the medium of language is but an attempt by the best of humans to have fellow-humans grasp principles that are beyond comprehension so long as we are in the dual mode. It would at best give us the direction towards which we may tread till finally we reach the realm of non-duality where symbols become redundant and we are one with existence. Therefore words have to be used as stepping stones to the truth and are not truths in themselves.
