When a Kālacakra maṇḍala is imagined in meditation, drawn, painted or built in 3D, very often the deities are formed from or represented by their seed characters. These seeds are all given in the listing of the deities of the maṇḍala to be found here.
When representing these seeds in artwork, one of the most favoured styles is to use Indian Lantsa characters (ornamental script, or Ranjanā script). The traditionally drawn calligraphy presented here was produced in Kathmandu for use in constructing a three-dimensional Kālacakra maṇḍala in Dzamthang, Eastern Tibet. The copies used here were kindly provided by Khenpo Choenang, abbot of Jonang Takten Phuntsok Choeling, in Shimla, who had commissioned and overseen their production. These seeds are not computer generated and are all hand drawn and then scanned. They therefore appear with rather rough edges when enlarged, as here. Some tidying-up has been done of any obvious artefacts; otherwise they have been left unedited. The seeds are given starting from the centre of the maṇḍala, the mind maṇḍala. Each one is given with the transcription of the seed character, its direction in the maṇḍala, and the Sanskrit and Tibetan names of the relevant deity.
At present (November 2013), only the seeds of the mind maṇḍala are presented here. The others will follow in due course. The heart seed of Kālacakra, "huṃ", is given at the top of this page; that image courtesy of the Nepal Research Centre. For more information on this seed, see this article.
