Shiva has always been referred to as Triambaka because he has a third eye. The third eye does not mean someone’s forehead cracked and something came out! It simply means another dimension of perception has opened up. If your perception has to evolve and enhance itself, the most important thing is that your energy has to evolve and enhance itself. The whole process of yoga is to evolve and refine your energies in such a way that your perception is enhanced and the third eye opens.
