Archaeologists working in a high-altitude monastery in the Spiti Valley have recovered a rare 9th-century manuscript written in the Sharada script. The text, titled Prana-Sanchara, contains lost Sanskrit treatises detailing the systematic study of plant-signal transduction—how plants perceive and respond to environmental stimuli. The manuscript describes experiments involving the application of various minerals and sound frequencies to induce specific growth responses in medicinal flora.
This discovery confirms that early Indian botanists had developed a conceptual framework for plant 'neurobiology', treating the flora as sensitive, communicative organisms. The research team is currently using multispectral imaging to preserve the fragile birch-bark leaves, which also contain detailed diagrams of the internal vascular systems of several extinct alpine plant species.
