Saundaryalahari of Shankaracarya
The Saundaryalahari has fascinated and puzzled generations of scholars and laypersons; subject to continuing study and debate, till today, such details as the authorship of the 100 verses named the Saundaryalahari remain a matter of contention, particularly among scholars.
While some attribute it to Shankara, others argue that the Saundaryalaharis verses in praise of the Devi cannot have been authored by this staunch Vedantin; some argue that it's value is essentially in the realm of what is loosely called "tantra," while others extend the significance of the Saundaryalahari to include the preoccupations of Vedanta.
Nataraja Guru is unequivocal in his belief that none other than Shankara could have composed this masterpiece of mystical poetry and identifies internal evidence in the verses themselves to support this view.
The detailed commentary views the Saundaryalahari as Advaita Vedanta itself, presented in a pictorial language and the beauty of the goddess as an objective representation of the Absolute joy of the Advaita.
