Why Did Hanumanji Tear Open His Own Chest?

You must have seen this photo.
Hanumanji tearing open his chest and the Lord's image is there inside.
Do you know the background of this?
Sri Rama Pattabhisheka was going on.
The Lord was seated on the simhasana.
Hanumanji was sitting near his feet on the floor.
The Lord's right foot was resting on Hanumanji's folded palms.
Bhagawan told Seetha matha: if you want to give something to Hanuman, you can give it now.
Matha took out a beautiful, invaluable garland of pearls from her neck and put it around the neck of Hanumanji.
Everyone started praising the garland and said it was so invaluable, so precious.
Hanumanji started wondering, in this world only that is precious which has the Lord inside.
Be it a being, be it an object, for that to be precious, the Lord should be there inside.
Hanumanji became curious.
Then these pearls should have the lord inside him.
Hanumanji with his teeth, gently broke one of the pearls, in the garland, to check whether the Lord was inside.
No. he was not there.
Then he broke open another pearl. No. the Lord was not there.
By this time, Vibhishana interfered: Hanuman, what are you doing?
Why are you destroying that precious garland?
Hanumanji said it doesn't look precious to me.
The Lord is not there inside.
Oh! If that is the case, are you sure the lord is there inside your body?
I don’t know.
But if he is not there, then I don't want this body anymore.
Then with his own nails, Hanumanji tore open his chest.
The Lord was there inside, for everyone to see.
Just as he was seated on the simhasana, he could be seen inside Hanumanji's s chest also.
He is always there in Hanumanji's heart.
Later, the Lord touched Hanumanji's chest with his own hand and there was not even a scar left.
Then the Lord himself put the garland around Hanumanji's neck.
