Who is Madame Blavatzky from Concerning the Spiritual in Art and what is their importance?

Madame Blavatzky explored the connection between primitive and modern civilization in India. She gave rise to a spiritual movement called the Theosophical Society that consists of groups trying to find answers to various problems through the spirit, using certain inner knowledge. They use various methods that are mostly derived from ancient wisdom. Such wisdom involves formulas that have a considerable precision. She created the theory of Theosophy that provided the basis for the movement, devising certain rules involving answers that incorporate the theosophical point of view. According to Blavatzky, Theosophy involves eternal truth, as such answers find everybody prepared for their acceptance while enabling them to combat various difficulties.
