Symbolism of the five Dhyani Buddhas

The five Dhyani Buddhas are mentioned in most of the tantric systems and represent various physical and mental aspects. Here are given only some of the most common explanations and representations of these so-called 'Heads of the five Buddha-families'.

It should be noted though that many different forms of each deity exist, and different tantras can have slightly different explanations (for example, in the Kalachakra tantra, six Dhyani-Buddhas are mentioned, and most have different colors and shapes).

The five Dhyani-Buddhas are also often found on the crown on the head of tantric Buddhas, like this:
