That is, the lower part of Shivlinga symbolizes female and upper part symbolizes male. Meaning, Shiva and Shakti live together in it.
According to the scriptures, the word ‘Lingam’ is composed of ‘Lia’ and ‘Gamya’ which means ‘beginning’ and ‘end’. In all the Hindu religion books it is described that the universe has appeared from Shiva ji and one day everything will be found in them.

The oval of Shivlinga, has both spiritual and scientific reference. Shiva is the root of the creation of the universe if seen spiritually. That means Shiva is that seed, from which the whole world is yielded. That’s why it is said that this is why Shivling is shaped like an egg. Same if scientifically speaking the ‘Big Bang Theory’ says the universe is formed from small particles like egg.
