In this scholarly and philosophical work, the author has focused on certain aspects of Sri Aurobindo's aesthetic philosophy: poetic discourse, imagination, poetry as mantra, and the value of art for spiritual life. He approaches his subjects through the lens of Sri Aurobindo's writings on evolutionary metaphysics and the sociology of human development. His main interest is Sri Aurobindo's theory of poetry, and he includes in his study an examination of the mystery of language, the function of imagination as the formative power of art, and the roles of reason and intuition in man's mental and artistic progress.
