Roman Catholics celebrate the Assumption of the Blessed Virgin Mary today. This is a day of obligation celebrated by fasting and the chanting of the Glorious Mysteries of the Rosary. Srila Prabhupada has this to say about the rosary:
Therefore, even if you accept designations like "Hindu," "Christian," or "Muhammadan," if you simply chant the name of God found in your own scriptures, you will attain the spiritual platform. Human life is meant for self-realization—to learn how to love God. That is the actual beauty of man. Whether you discharge this duty as a Hindu, a Christian, or a Muhammadan, it doesn't matter—but discharge it!
Father Emmanuel: I agree.
Srila Prabhupäda [pointing to a string of 108 meditation beads]:
We always have these beads, just as you have your rosary. You are chanting, but why don't the other Christians also chant? Why should they miss this opportunity as human beings?
