Vaastu differences

Why is it that every finance ministry official who moves to the Reserve Bank of India as governor turns against the finance minister who is the most responsible person for appointing him? Y V Reddy, D Subbarao and now Raghuram Rajan - all stop seeing merit in many of the things the finance ministry suggests. Subbarao, who had helped mend relations between the North Block and Mint Road when Reddy was governor, turned down a proposal he had moved as finance secretary after he became governor. Rajan reportedly also has different views on some issues. A government official quips that it's all in the vaastu - the Indian doctrine that determines the relationship of the elements of nature to buildings - which is a useful way of explaining the inexplicable.
