Answer by Niraj Bidawatka:
There are five types of mukti – sayujya, samipya, salokya, sarsti and sarupya.
When you say moksha, it connotes or is generally understood to be sayujya mukti.
Otherwise, mukti and moksha are the same. But when you go deeper into its understanding, the connotation of moksha is sayujya mukti.
The pure devotees do not accept any of the five muktis: “diyamaanam na grihnanti“
