LUCKNOW, India (Reuters) - When Amit Shah, president of Narendra Modi's ruling party, meets with the Indian prime minister, he is sometimes asked a question he struggles to answer: "What is behenji thinking?"

By "behenji", or "older sister", Modi means Mayawati, the enigmatic politician and former ruler of India's most populous state, Uttar Pradesh.
