I try to keep negativity away from my thought process: Ashwin

Ravichandran Ashwin, with 489 Test wickets and 151 ODI scalps, has been through a lot in the last few months. The 36-year-old was not considered for the World Test Championship final, came back strong in the West Indies Test series after that, and now he is not in India's scheme of things for the World Cup in October-November.
