When Parvati met Shiva, he had spent thousands of years in deep meditation and Yoga atop Mount Kailasha, removing himself from the world completely. But Parvati wanted to bring Shiva closer to the world because she understood that those years had given Shiva a phenomenal perspective and understanding of reality.
A perspective which could help the world.
So Parvati became a devoted student of Shiva. She would ask him questions about the cosmos. Sitting on Kailasha, Shiva answered every question she had, explaining the secrets of the cosmos to her in the process. With every answer, great truths were revealed - not just to Parvati, but to the world. These were the truths Shiva had discovered during his thousands of years of meditation. And as he answered Parvati, Shiva started coming closer to worldly matters.
After some time, he made an announcement to the world, revealing this Truth:-
"He who escapes from joy and sorrow instead of living and dealing with them, is a fool and he shall forever fail to see the truth. And he who is only a part of pleasures and pains of life, is also a fool, he shall also never discover the truth. The truth lies in balance, in harmony, between body, mind and soul. It is the balance between individual and society."
The Meaning:-
While revealing the Truth of balance (Sayyam) to the world, Shiva makes an important point we must all learn from:-
Your power is not in removing yourself from the joys and sorrows of the world. Nor is it in extreme meditation or renunciation, nor in the complete immersion of physical life, at the expense of the soul. Your power is found in the balance of all things. This is where you find the truth of YOU.
This means that we must always enjoy the pleasures and the sorrows of life, while balancing them with meditation and discovery of the self.
Lord Shiva's balance:-
While Shiva is the one to whom all other gods turn when the world is in trouble, he is also the one they are afraid of when he is making love to his wife!
As a passionate lover and an ever-present ally, Shiva is a multi-faceted god. As an ascetic he renounces all worldly pleasures and lives on the peak of Mount Kailash (his abode) meditating with great intensity. But while he is with his wife, he is a lover, a great friend and a compassionate listener. He manages these seemingly contradictory qualities through balance.
But more important than a balance to opposite behaviors is a balance of emotions. Love is very POWERFUL. When love is combined with passion, it can fill you with joy. Sadly, it can also drive you to utter despair or even destruction. Thus it must be channeled properly in order to lead you to balance and success.
