Why does the astrologer choose the profession of fortune-telling in "An Astrologer's Day" by R.K. Narayan?

He embraces fortune-telling as a lifelong ambition, seeking wisdom from the stars

The astrologer becomes a fortune-teller to escape a troubled past, meeting a skeptical stranger.

He turns to fortune-telling for financial reasons, encountering a former client seeking revenge.

The astrologer chooses this profession due to a family tradition and a police officer's suspicion.
