When his rivals were at their resistance-obstruction-height, Subhas Chandra's heart was all concern for Gandhi-ji's health. One day, when the Mahatma had a fever, Subhas wrote to him with utmost devotion:
"I am feeling anxious about your fever. I am praying that it may soon disappear. With respectful pranams,
  Yours affectionately,
  Subhas"

Alas, when Subhas was a victim to high fever and sickness, his fate was otherwise.
