May 29th marks the anniversary of the ascension of Bahá'u'lláh from this earthly plane of existence.  Baha’u’llah passed away after a brief illness in 1892 in the mansion of Bahji outside Akka, in what is now northern Israel. After spending most of His life in exile, He was able to live his later years at Bahji in relative tranquility. He was buried in a small stone house adjacent to the mansion, which now serves as the point of adoration for all Baha'is.  
 
Six days before His death, Baha’u’llah gathered his followers and family members and delivered what would be His last address to them:

"I am well pleased with you all. Ye have rendered many services, and been very assiduous in your labors. Ye have come here every morning and every evening. May God assist you to remain united. May He aid you to exalt the Cause of the Lord of being."

The commemoration will be held at the Washington DC Baha'i Center on Sunday May 29th at 3 am.  A devotional program will begin at 3:15 and will culminate with a reading of the Tablet of Visitation at 4 am. For more on the life of Baha’u’llah visit: bahaullah.org.
