In the Buddhist Tantra, Vajra symbolizes invincible and indestructible wisdom and true Buddha-like nature, which can cut off all kinds of troubles, destroy all kinds of obstacles to the cultivation of demons, as the holding of the Buddhist Buddha or yogi practice. The Vajra Division of the Mandala Sea Council has a Vajra pestle. The truth-talkers also often carry this pester to symbolize the Tathagata's diamond wisdom, which is used to break the inner demons and outer demons of the foolish delusion.
