Total absorption in hearing Sankirtana Music develops faith in Lord Krishna.
When we face difficulties and still remain faithful to Krishna and the spiritual master, we access the infinite mercy of their hearts.
No one lives even a moment without faith, even unconsciously.
Faith means… unflinching trust in something sublime.
Bhagavad Gita 2.41,
To the extent the heart is polluted with sins, it cannot place its faith in the vedic scriptures or the bonafide spiritual master.
Feed your faith, your doubts shall starve to death.
