Integral yoga, sometimes also called supramental yoga, is the yoga-based philosophy and practice of Sri Aurobindo and The Mother (Mirra Alfassa). Central to Integral yoga is the idea that Spirit manifests itself in a process of involution, meanwhile forgetting its origins. The reverse process of evolution is driven toward a complete manifestation of spirit. According to Sri Aurobindo, the current status of human evolution is an intermediate stage in the evolution of being, which is on its way to the unfolding of the spirit, and the self-revelation of divinity in all things. Yoga is a rapid and concentrated evolution of being, which can take effect in one life-time, while unassisted natural evolution would take many centuries or many births. Aurobindo suggests a grand program called sapta chatushtaya (seven quadrates) to aid this evolution. Worldview Spirit - Satchitananda Spirit or satchitananda is the Absolute, the source of all that exists. It is the One, having three aspects: Sat (truth), Citta (consciousness, awareness), and ananda (bliss, happiness). Involution Involution is the extension of Spirit, the Absolute, to create a universe of separate forms. Being manifests itself as a multiplicity of forms, meanwhile becoming lost in the inconscience of matter. The first manifestation of Spirit in the process of involution is as Satchitananda, and then as Supermind, the intermediate link between the higher (Spirit) and lower (matter, life, and mind) nature. According to Aurobindo the world is a differentiated unity. It is a manifold oneness, that generates an infinite variety of lifeforms and substances. The lifeforms and substances are stretched out on a wide range, from physical matter to a pure form of spiritual being, akin to the five koshas or sheaths, where the subject becomes fully aware of itself as spirit: Material: a submerged consciousness concealed in its action and losing itself in the form. Vital: an emerging consciousness, a consciousness half delivered out of its original imprisonment which has become of vital craving and satisfaction or repulsion. Mental: an emerged consciousness reflecting fact of life in a mental sense, perceptive and ideative. It modifies the internal and attempts to modify conformably the external existence of the being. Above Mind proper lie various higher levels of Mind, which ascend toward Spirit. Evolution Through evolution Spirit rediscovered itself as Spirit. Evolution follows a developmental trajectory from the original inconscience of matter into life, to mind, and then to spiritualized mind, culminating in The
