Very happy to present this sloka from Saundaryalahari composed by Sri Adi Sankara. This sloka is a prescription for those who lost their voice or who wants to improve their voice or wants to retain their voice.This sloka brings out the beauty of Devi's vaak. A beautiful explanation for this given by Sri Kanchi Paramacharya( Sri Chandrasekharendra Saraswati Swami) is furnished here.
I recorded this sloka for Smt Ganga Rajan, a senior music teacher from Mumbai who wanted me to sing this for the benefit of all! Feel grateful to Ambal and her!
