intuitive dreams, clairvoyance, telepathy and creative insight. It is developed naturally through psychic clash, and in Ananda Marga sadhana by methods of pratyahara (withdrawal) such as shuddhis and Guru Puja. Vijinanamaya Kosa ("layer of the special knowledge") or "Subliminal Mind": is the layer of conscience or discrimination (viveka) and vaeragya (non-attachment). This Kosa is developed naturally through psychic clash, and its development is accelerated by the process of dharana. Hiranyamaya Kosa ("golden level") or "Subtle Causal Mind": is the subtlest layer. Here the awareness of mind is very close to the direct experience of "Supreme Consciousness". Here there is only the separation of a thin veil of ignorance. This Kosa is developed naturally through the attraction for the Great, and dhyana accelerates this process for sadhakas (spiritual aspirants). Biopsychology Sarkar's "biopsychology" reimagined the traditional tantric belief in chakras ("wheels") as being due to interactions of subtle energies through nerve plexuses. He believed this connected the endocrine glands of the neuroendocrine system with a psychic part of the body. The philosophy of Ananda Marga considers the human body as composed of the same five fundamental factors as the rest of the universe as explained in Brahmachakra. Every factor is said to be distributed throughout the body, but governed by a chakra, substations of the mind which control their own assigned areas. The biopsychology of Ananda Marga expands the concept of the seven basic chakras and in general, mainly considers: The Muladhara Chakra: at the tip of the spine (controls the solid factor). The Svadhisthana Chakra: at the level of the genitals (controls the liquid factor and is associated with the reproductive glands). The Manipura Chakra: at the level of the navel (controls the luminous factor and is associated with Pancreas). The Anahata Chakra: at the center of the chest (controls the aerial factor and is associated with Thymus). The Vishuddha Chakra: at the throat (controls the ethereal factor and is associated with the Thyroid gland). The Ajina Chakra: between the eyebrows (associated with the Pituitary gland). The Sahasrara Chakra: at the crown of the head (associated with the Pineal gland). Mind's propensities (vrttis) associated with each Chakra affect the glands and the hormones secreted from those glands (hence the emotions, physical behaviour and functioning of the various body systems). But the glands and the hormones they secrete may also affect the mind in a chain of feedback. Microvita "Microvita" is plural
