Jai Sri Ganesha,
Light divine is referred to the light of God,
Shabd Brahma possesses them both yet light relates to God and Sound cause for spirit and material,
Basically, both light and sound found themselves lost in the gross matter and in that matter dwells the light of atman that activated through a hidden cord,
On indifferent pitches, worldly music dwells whereas celestial melodies are pitched at specific pitches to reach, and celestial events and occasions make them manifest for devotees and aspirants that to oblige them,
May Lord Bless all,
Thanks, please
