Myth regarding the Kusha Grass
In Vedic literature like the Puranas and the Upanishads it is described that the kusha grass came into existence during the Samundra Manthan, churning of the cosmic seas. When the gods and demons got ready to churn the cosmic ocean there was nothing to support the base of the Madhara Mountains. So, Lord Vishnu assumed the form of the Cosmic Tortoise (Kurma Avatar) and the shell of the tortoise gave the needed support. During the churning, the hairs of the tortoise rubbed off and were washed ashore and became Kusha. When Amrita, the nectar of immortality was finally achieved, few drops of it fell accidentally on the Kusha grass thus imbuing it with healing properties. The serpents around wanted a taste of this elixir and ended up licking the leaves, but they were so sharp that the serpent"s tongue were sliced in two.

The Kusha grass with all its healing potency and religious uses is grown on low-lying marshy regions and is available all over India.
