Mahashivratri is an ecsatic celebration of masculine creative power of Shiv merging in perfect harmony with the feminine creative energy of Shakti. The union of ShivShakti is bliss to life.
Shiv-Shakti abound each and everything that is.
Needless to add that it is present in equal measures in each one of us too. We just need to consciously fine tune or balance the supra natural powers in us by finding our own ways to be in peace and bliss.
Life then is a perfect symphony...
