The trident of Shiva is the symbol of the three qualities of Nature, the three gunas, and hence the three functions of Creator, Preserver, and Destroyer. In the microcosm the trident represents the three subtle arteries of the body, ida, pingala, and susumna, which, according to the theory of yoga, ascend from the root center at the base of the spinal cord to reach the "lotus of a thousand petals" at the summit of the head. The trident is also the giver of punishment on the spiritual, subtle and physical planes. Sanskrit for punishment is 'shula', hence the trident is called 'trishula', tri = three. As the trident bearer Shiva is known as 'Shulin'. OM is the symbol of essence of Hinduism. It means oneness with the Supreme, the merging of the physical being with the spiritual. It is the most sacred syllable, the first sound of the Almighty. Swastika means luck or auspicious object, and in particular a mark made on person and things to denote good luck.
