Question: Are we not able, through love and faith, to make those on the other side hear of the Cause who had not heard of it while on earth?
‘Abdu’l-Baha: Yes, surely sincere prayer always has its effect, and it has a great influence in the other world. We are never cut off from those who are there. The real and genuine influence is not in this world but in that other.
