The line — '…I can't see how talking to astrologers will bring rain' — tells us that Velu is a practical, rational man who trusts experience and evidence rather than ritual.
- He gives a reason rather than simply refusing: 'The rains came all these years without any such consultations.' That is an argument from evidence — it worked before without astrologers, so astrologers are not the cause.
- He is not mocking anyone. His neighbours' suggestion is met with disagreement, not contempt.
- And he does not simply reject and sit still. He immediately looks for a better source of information and travels to the weather office in the city.
