FTA, problem-solving angle tangential to Sanskrit:

> Mr Rajpopat said he had "a eureka moment in Cambridge" after spending nine months "getting nowhere".

> "I closed the books for a month and just enjoyed the summer - swimming, cycling, cooking, praying and meditating," he said.

> "Then, begrudgingly I went back to work, and, within minutes, as I turned the pages, these patterns starting emerging, and it all started to make sense."

Sometimes the best thing to do after grinding is to just walk away for awhile.
