Three Jewels and Three Roots
In Tibetan Buddhism, the Three Jewels and Three Roots are supports in which a Buddhist takes refuge by means of a prayer or recitation at the beginning of the day or of a practice session. The Three Jewels are the first and the Three Roots are the second set of three Tibetan Buddhist refuge formulations, the Outer, Inner and Secret forms of the Three Jewels. The 'Outer' form is the 'Triple Gem', the 'Inner' is the Three Roots and the 'Secret' form is the 'Three Bodies' or trikāya of a Buddha.
