The word Trishul finds its origin from the Sanskrit word 'Tri' meaning three and 'Shul' meaning a spiked weapon. Consequently, this three-edged spiked weapon resembles a trident. Indian mythology has it that the Trishul was a powerful and all pervasive weapon of the Lord Shiva, that was effectively used by him to ward off evil. The Trishul as a weapon has been used ever since then to symbolize the victory of truth and righteousness over evil. According to mythology, surviving the onslaught of the Trishul is impossible. The crest of the ship depicts a strong arm rising out from under the sea, holding the powerful Trident. The mythological truth of this feared weapon, when extended to the INS Trishul makes the ship powerful in all three dimensions - air, surface and sub-surface. A warship that will be feared for her lethality and brutal power.
