Chakrology
Chakrology (from the Sanskrit Chakra=wheel and the Greek Logos->logy) is a modern word (neologism), some times used by Alternative Medicine practitioners or esoteric philosophers, for the study of chakras.
There are many different chakrologies, some of them based on ancient Indian Tantric esoteric traditions, New Age interpretations, Western occult analyzations etc.
The early chakrologies include the Tantric Shakta theory of chakras, some late Upanishads (such as the Brahma Upanishad and the Yogatattva Upanishad) and Tibetan Buddhism (Vajrayana) theories.
There are references for ancient Greek and Christian chakrologies too. An example is the Hesychastic centres of prayer, [1].
As the Croatian esoteric philosopher and physicist Arvan Harvat states, it is very difficult to develop a unified coherent chakra science that would integrate all the elements of present chakrologies.
