A couple examples come too mind from Amma's later life of how she showed her love by going well beyond what could be expected in those situations.
My son and I flew into Chennai on August 2nd, 2010 in the very early morning, just a couple hours past midnight. Amma was in the middle of her chemotherapy treatment after having undergone surgery just a couple months earlier. It was between chemo sessions, so she was home. She usually came to the airport to receive us, and that was the very first time she did not do so. When we arrived home in the middle of the night, she was ready - cake in hand, candles ready - determined to celebrate my birthday (August 1st) only a few hours late. Chemo side effects be damned, she was not going to miss the opportunity.
Going the extra mile for her sons was second nature to Amma, past every trial and tribulation that life threw at her, and down to her last breath.
