The word Anand in Sanskrit and other Indian languages (e.g. Hindi) translates to bliss. In vedanta philosophy there is a discussion of 5 koshas where the innermost kosha is Anandmaya kosha. So firstly why is this (Anandmaya) a separate 5th kosha? Isn't bliss also a state of mind (part of Manomaya kosha)?
Then the atman/ purush/saakshi resides within the panch-kosha as in the koshas are external to atman. This creates further confusion since atman is same is brahman which is sat-chit-ananada. Now is ananda in sachchidananda same or different from the anandmaya kosha?
Edit : My real query is about the understanding of the true meaning of word 'ananda'. The suggested links don't discuss that explicitly I think.
