Hanuman was a loyal follower of Rama and worshipped him
wholeheartedly. One day, Sita gave him a precious pearl necklace. Hanuman
immediately broke the necklace and started looking at each pearl
carefully. He glared at each pearl and threw them away, one by one, in
disgust. Sita was surprised and asked him for an explanation.
Hanuman explained that he was looking for Rama's image in the pearls.
Hanuman believed that Rama was present everywhere and was disappointed
that he could not find his image in the pearls. He declared the pearls
were just stones and pebbles and thus, were worthless. When the people
around him asked if Rama was present in Hanuman, Hanuman tore open his
chest with his hands and everyone was amazed to see a brilliant image of
Rama and Sita engraved in his heart.
The people accepted that Hanuman was a true devotee of Rama. This is
why he is also known as Bhakta Hanuman.
