‘Abdu’l-Bahá said: Those who are working alone are like ants, but when they are united they will become as eagles. Those who work singly are as drops, but, when united, they will become a vast river carrying the cleansing water of life into the barren desert places of the world. Before the power of its rushing flood, neither misery, nor sorrow, nor any grief will be able to stand. Be united! It is rather dangerous to be an isolated drop. It might be spilled or blown away.
(Lady Blomfield, The Chosen Highway, p. 171)
No one can on his own achieve anything. ‘Abdu’l-Bahá must be well pleased and assist.
(‘Abdu’l-Bahá, The Compilation of Compilations vol II, p. 362)
