Happy Ridvan to my fellow believers in the One True God. Ridvan is the most important feast in the Baha'i Faith. It's when we commemorate that time in the Garden of Ridvan when Baha'u'llah revealed Himself and His mission to a small group of disciples. Similar to The Lord Jesus in Gethsemene
I am not familiar with with the holiday, but I hope you had an enjoyable one if it has special meaning for you. God's peace.
