Savitri, the epic of the future, stands on "Sri Aurobindo's new concept of poetry and his Overmind aesthesis".
From the 'Apologia':
The present volume deals with Sri Aurobindo's new concept of poetry of the future - its 'laws' of composition and the new aesthesis. It also deals with the form, design and structure and technique of Savitri along with its thematic scheme. The purpose is to provide a foothold that the readers might require to have some sort of understanding of Savitri as an epic poem.
The book has been mainly prepared in view of the need of students and of common readers of poetry, specially of Sri Aurobindo's poetry.
