According to medical intuitive and author, Caroline Myss, who described chakras in her work Anatomy of the Spirit (1996), "Every thought and experience you've ever had in your life gets filtered through these chakra databases. Each event is recorded into your cells...", in effect your biography becomes your biology.
The chakras are described as being aligned in an ascending column from the base of the spine to the top of the head. New Age practices often associate each chakra with a certain colour. In various traditions chakras are associated with multiple physiological functions, an aspect of consciousness, a classical element and other distinguishing characteristics. They are visualised as lotuses/flowers with a different number of petals in every chakra.
The chakras are thought to vitalise the physical body and to be associated with interactions of a physical, emotional and mental nature. They are considered loci of life energy or prana, also called shakti, qi (Chinese; ki in Japanese), koach-ha-guf (Hebrew), bios (Greek) & aether (Greek, English), which is thought to flow among them along pathways called nadis. The function of the chakras is to spin and draw in this energy to keep the spiritual, mental, emotional and physical health of the body in balance. They are said by some to reflect how the unified consciousness of humanity (the immortal human being or the soul), is divided to manage different aspects of earthly life (body/instinct/vital energy/deeper emotions/communication/having an overview of life/contact to God). The chakras are placed at differing levels of spiritual subtlety, with Sahasrara at the top being concerned with pure consciousness, and Muladhara at the bottom being concerned with matter, which is seen simply as condensed, or gross consciousness.
In his book on Japa Yoga, Himalaya Press 1978, Swami Sivananda states that a yogi that practices Japa with only the Om and is successful at Mahasamyama {oneness with the object...in this case a Word being meditated on} becomes a direct disciple of that, the OM, the most Holy of all words/syllables { the same as the word of creation as recognised by the Torah, although this is not professed or quite possibly not even recognised by those of secular authority in either Judaism or Christianity} thus the yogi achieving this feat needs no Guru or Sat-guru* to achieve any Spiritual goal {*Archetype / Ascended Master i.e. A Krishna, a Rama, a Jesus, a Nanak a Buddha..et al.} and Swami Sivananda mentions that this yogi has a path that is, in all recognisable ways and manners, reverse of that of other Yogis or Spiritual aspirants and their paths and those include all Christian ascetics, in that this spiritual aspirant then works through the chakras, mastering them from the crown down. Satprem explains in page 67 of his book "Sri Aurobindo or the Adventure of Consciousness"(ISBN 81-85137-60-9), in Sri Aurobindo and the Mother's Integral Yoga the practitioner experiences a "descent" where the Grace and Light works through and enlightens the chakras from top crown chakra downwords.
Whereas every other well known path and all major religion start by trying to master the chakras starting with the 'Svadhisthana Chakra' {Sex}, these Yogis aren't expected to renounce sex or certain foods, and by virtue of this they do not need to remove themselves from the world of temptations and become monks or recluses. They can stay in the world of men and live what appears to be a normal life that observes whatever local custom{s} there may be. Trevor Ravenscroft also mentions this spiritual goal and achievement in his book, "The Cup of Destiny", and says that these practices and achievements were known and the most highly regarded and desired by the Templar Knights of old.
New Age writers, such as Anodea Judith in her book Wheels of Life, have written about the chakras in great detail, including the reasons for their appearance and functions.
Another interpretation of the seven chakras is presented by writer and artist Zachary Selig. In the book Kundalini Awakening, a Gentle Guide to Chakra Activation and Spiritual Growth, he presents a unique codex titled "Relaxatia", a solar Kundalini paradigm that is a codex of the human chakra system and the solar light spectrum, designed to activate Kundalini through his colour-coded chakra paintings.
Some chakra system models describe one or more Transpersonal chakras above the crown chakra, and an Earth star chakra below the feet. There are also held to be many minor chakras, for example between the major chakras. Chakras are also used in linguistic programming to connect NLP logical levels with spiritual goals on the crown, intellectual on the forehead and so on.
Rudolf Steiner considered the chakra system to be dynamic and evolving. He suggested that this system has become different for modern people than it was in ancient times, and will in turn be radically different in future times. Steiner describes a sequence of development that begins with the upper chakras and moves down, rather than moving in the opposite direction. He gave suggestions on how to develop the chakras through disciplining the thoughts, feelings, and will.
According to Florin Lowndes, a 'spiritual student' can further develop and deepen or elevate thinking consciousness when taking the step from the 'ancient path' of schooling to the 'new path' represented by The Philosophy of Freedom.
