These books are an introduction to the study of the Philosophy and Yoga of Sri Aurobindo and the Mother who invite us to collaborate with the effort that is involved in the synthesis of Yoga that can liberate us from the fetters of dogmas and preconceptions and inspire us to realise the highest and the best not only for ourselves but also for the entire humanity. These books also include a study of the philosophy, education, Indian culture and teacher training based on the works of Sri Aurobindo and the Mother in order to give insights for the new roles of the teachers and new trends of the synthesis of East and the West, which would be agents of change from old to the new.
