The six schools of Hindu philosophy have many differences. As far as I know, a soul is an atom according to the Nyaya-Vaisheshika school. According to Samkhya, there are many souls, and they are pure consciousness. On the other hand, Advaita claims there is only one consciousness, and the rest is a delusion.
So, I guess the definition of Moksha or state of liberation might be different according to different schools. I am looking for authoritative verses from the Sutras and Karikas of respective schools describing the state of Moksha.
By the way, I am not talking about the different ways of attaining moksha according to different schools. It already has an answer here (What is the means of attaining Moksha according to the different Astika schools?). I wanted to know what different schools mean by Moksha? Interested to know Whether the definition varies. So my question is not a duplicate of that question.
