Re: For Mike: Esha & Asha
They look like they might be connected, but I cannot find anything concrete to link them. The Sanskrit roots are एष् (eṣ) for Esha and आशा (āśā) for Asha. Note that the consonant is different for each -- these were actually distinct sounds in Sanskrit.
Maybe someone with some familiarity with Sanskrit can describe if and how they are related?
