Literally "whirlpool", is a term meant to indicate that the contents of mental awareness are disturbances in the medium of consciousness.
Vritti can be taken as a catch-all term for any content in consciousness, where it is regarded as a medium or container for any possible mental content. The scope of the idea is very broad, referring not only to thoughts and perceptions experienced in a normal waking state, but also to all super-physical perceptions, such as dreams or in any altered state of consciousness.
