Very sweet! The "maun vyakhya samudit darpam" line in this rendition reminded me of Dakshinamurti strotam. Especially a verse from Dakshinamurti strotam, where Dakshinamurti Shiva is expounding Vedanta to Rishis.
"Chitram vata tarur moole
Vridhha shishya gurur yuvaa
Grusutu maunam vyakhyaanam
Shishyastu chinna samshaya"
The scene: under the vata treee, a young guru and aged disciples are sitting.
Guru is elucidating through silence, dispelling doubts of disciples.
