Sri Ramakrishna: "Listen to a story. Once a man entered a wood and saw a small animal on a tree. He came back and told another man that he had seen a creature of a beautiful red colour on a certain tree. The second man replied: 'When I went into the wood, I also saw that animal. But why do you call it red? It is green.' Another man who was present contradicted them both and insisted that it was yellow. Presently others arrived and contended that it was grey, violet, blue, and so forth and so on. At last they started quarrelling among themselves. To settle the dispute they all went to the tree. They saw a man sitting under it. On being asked, he replied: 'Yes, I live under this tree and I know the animal very well. All your descriptions are true. Sometimes it appears red, sometimes yellow, and at other times blue, violet, grey, and so forth. It is a chameleon. And sometimes it has no colour at all. Now it has a colour, and now it has none.' "In like manner, one who constantly thinks of God can know His real nature; he alone knows that God reveals Himself to seekers in various forms and aspects. God has attributes; then again He has none. Only the man who lives under the tree knows that the chameleon can appear in various colours, and he knows, further, that the animal at times has no colour at all. It is the others who suffer from the agony of futile argument. "Kabir used to say, 'The formless Absolute is my Father, and God with form is my Mother.' "God reveals Himself in the form which His devotee loves most. His love for the devotee knows no bounds. It is written in the Purana that God assumed the form of Rama for His heroic devotee, Hanuman.
