Read the excerpt from Jungle Book: Mowgli's Brothers.

The fire was burning furiously at the end of the branch, and Mowgli struck right and left round the circle, and the wolves ran howling with the sparks burning their fur. At last there were only Akela, Bagheera, and perhaps ten wolves that had taken Mowgli's part. Then something began to hurt Mowgli inside him, as he had never been hurt in his life before, and he caught his breath and sobbed, and the tears ran down his face.

"What is it? What is it?" he said. "I do not wish to leave the jungle, and I do not know what this is. Am I dying, Bagheera?"

"No, Little Brother. Those are only tears such as men use," said Bagheera. "Now I know thou art a man, and a man's cub no longer. The jungle is shut indeed to thee henceforward. Let them fall, Mowgli; they are only tears." So Mowgli sat and cried as though his heart would break; and he had never cried in all his life before.

Growing up can be lonely and painful.

Wise friends are a life-long treasure.

Explanation:

The first theme, that of growing up, is the most salient point Kipling leaves the reader with. It describes how Mowgli's loneliness almost physically hurts him, because he's grown close to his friends in the jungle, and he doesn't want to leave.

The next theme is more implied, but it's clear from Bagheera's comments. Bagheera says that Mowgli's tears are "only tears such as men use," which makes it clear that tears are not a sign of weakness but a sign of maturity in this case. Bagheera's wise insights comfort Mowgli, so it's a reasonable assumption that wise friends are a treasure.

glamis thou art, and cawdor; and shalt be what thou art promis'd; yet do i fear thy nature; it is too full o' the milk of human kindness to catch the nearest way: thou wouldst be great; art not without ambition; but without the illness should attend it. what thou wouldst highly, that wouldst thou holily; wouldst not play false, and yet wouldst wrongly win: thou'dst have, great glamis, that which cries, "thus thou must do, if thou have it: and that which rather thou dost fear to do than wishest should be undone." hie thee hither, that i may pour my spirits in thine ear; and chastise with the valor of my tongue all that impedes thee from the golden round, which fate and metaphysical aid doth seem to have thee crown'd withal.
