Did you hear a particularly good point in the sermon you heard at Mass to fulfill your Sunday obligation?
Meanwhile, here is something for your edification. This is the third of the five prayers of blessings of candles during Mass, Candlemas.
Let us pray. O Lord Jesus Christ, the true Light who enlightenest every man that cometh into this world: pour forth Thy blessing + upon these candles, and sanctify + them with the light of Thy grace, and mercifully grant, that as these lights enkindled with visible fire dispel the darkness of night, so our hearts illumined by invisible fire, that is, by the splendor of the Holy Spirit, may be free from the blindness of all vice, that the eye of our mind being cleansed, we may be able to discern what is pleasing to Thee and profitable to our salvation; so that after the perilous darkness of this life we may deserve to attain to neverfailing light: through Thee, O Christ Jesus, Savior of the world, who in the perfect Trinity, livest and reignest, God, world without end.
