How sound engineering affects mind & body by chanting or visiting the sanctum sanctorum of a temple

Excellent scientific description as to how sound engineering affects our mind and body by chanting Vishnu Sahastranam and Lalita Sahastranam AND by visiting the sanctum sanctorum of a temple. A must hear and see and to be shared widely. Probably the first time some one has attempted a scientific explanation for the blissful experience of reciting mantras and on visiting temples. Simply brilliant. 🙏👍🙏
