The 63-folio manuscript made of palm leaves, written about 120 years ago, reveals 48 mantras on how to use the weapons like brahmastra, varunastra, agneyastra and nagpash mentioned in epic Mahabharata.
A R Krishnakumar, project manager at the Central Council for Research in Ayurvedic Sciences (CCRAS) said the valuable manuscript was found at the time of digitising collections of Namobbodiri using the reprography method, the report said.
Krishnakumar also said that Namboodiri's wish was to digitise all his manuscript collections.
Krishnakumar is a member of the team from the Indira Gandhi National Centre for the Arts which has been assigned the task of digitising manuscripts available in public and with private parties in the country, the report added.
The discovered manuscript has 48 mantras on how to use the weapons
The CCRAS official said that not even 15 per cent of the information received from manuscripts written on ayurveda has been used despite it being a popular system of medicine. He said ayurveda's effectiveness will increase in leaps and bounds if that number goes up significantly.
