Explanation:

Statement 1: Integral Yoga is a system of Yoga that synthesizes six branches of classical Yoga philosophy and practice: Hatha, Raja, Bhakti, Karma, Jnana, and Japa Yoga.His main literary works are The Life Divine, which deals with theoretical aspects of Integral Yoga;Synthesis of Yoga, which deals with practical guidance to Integral Yoga; and Savitri: A Legend and a Symbol, an epic poem.
Statement 2: Sri Aurobindo argues that divine Brahman manifests as empirical reality through leela,or divine play.Instead of positing that the world we experience is an illusion (maya), Sri Aurobindo argues that world can evolve and become a new world with new species, far above the human species just as human species have evolved after the animal species.
Statement 3: Sri Aurobindo believed that Darwinism merely describes a phenomenon of the evolution of matter into life, but does not explain the reason behind it, while he finds life to be already present in matter, because all of existence is a manifestation of Brahman.He argues that nature (which he interpreted as divine) has evolved life out of matter and then mind out of life.
