Summoning heading
This is a study piece which brings together a traditional heading character with the invocation syllables dzaḥ hūṃ baṃ hoḥ,
placed above each swirl of this character.
More common is a heading character of two or three swirls, typically to announce the very start of a major Tibetan manuscript, such as a sutra.
