I am very glad to note that Sarasvati Mahal Manuscript Library brings to the light a small but rare and worthy book named " MAITREYI - BRAHMANA BHASHYA. - TATPARYA DEEPIKA " of Sri Mahadevendra Sarasvati an acclaimed exponent " Advaita Vedanta ".
The Sanskrit word " BRAHMANA " means a portion of the Veda which states rules for the employment of the hymns at the various sacrifices, their origin and detailed explanations' with sometimes lengthy illustrations in this shape of legends or stories or dialogues.
This book reveals the essence of dialogue between MAITREYI (The wife of sage Yagna-valkya) and Yagnavalkya the great preceptor of Advaita Philosophy. The dialogue described in chapters 2-4 and 4-5 in BRUHADARANYAKA UPANISHAD is summarized in 150 verses by Sri Mahadevendra Sarasvati.
The introduction in English provides an introductory to the essentials of Advaitha Philosophy.
I hope this book will be welcomed by the disciples and students of Advaita Vedanta. The editor richly deserves sincere appreciation.
