A Cerean holding a Kasha crystal The kasha crystal served as a conventional meditation aid for the Cerean people. Their purpose was to eliminate mental diversions, thereby fostering an ideal setting for meditation. To fully exploit the crystal's energy, designs were etched onto each of its surfaces, perhaps crafted by Bi-Dar Tyunda millennia ago.
Acting as a lightsaber crystal, it aided in focusing the user's thoughts, even amidst intense battle situations.
