Ramakrishna Paramahamsa, The Gospel of Râmakrishna — Chapter 1
“ When an elephant is washed, immediately he throws dust and dirt over himself; but if he is kept in a clean stall after his bath, then he cannot cover himself with dirt. By the power of the Holy Name a man may be purified, but he may once more commit sinful acts because his mind is weak. He cannot promise that he will never sin again. The water of the Ganges may wash away past sins, but there is a saying that sins perch on the top of trees. When a man comes out of the Ganges and stands under a tree, the sins drop over his shoulders and seize upon him ”
