Just like the greeness that is ever present in the trees and the shrubs is made apparent and freshened by a downpour, sathgurUs and nAdhOpAsakAs who sing the praise of the Lord through krithis rich in swara ,rAga and lAya ,bring out the divinity that is ever-present in us.

Just like the dark-hued rain bearing clouds driven by the trade winds(which become podhigai Thendral) please the farmers who work hard in the fields, the wind of bhakthi triggered by a guru gives infinite happiness to the samsArin when he gets the vision of the dark-hued lord.
