I think you have something backwards here.

Spelling his name "Paramhansa" is the misspelled version.
The correct version being,"Paramahansa."

Without the silent a that was originally left off the word really means nothing of any significance. And is usuitable to define a yogi of Yoganandas stature.

This Change was a major correction to this problem.
The spelling with 4 A's is a Bengali, provincial variation,
Yogananda was anything but provincial....
