Tom: Is there even such a thing as Moksha? Even to speak of Moksha is more ignorance, as it implies some entity that can be liberated, or something to be liberated from.
However…In more conventional terms we could say there are no levels of Moksha (as there is only Moksha), but there are various levels of ignorance. So all apparent levels of realisation appear in maya/are illusory/are based in ignorance.
Gaudapada in his commentary of the Mandukya Upanishad hints at this: see the first 2 verses I quote from him here together with my commentary: Advaita Vedanta: Gaudapada’s Method
There are various stages that the seeker tends to go through, however, see this link for more: Q. What are the stages of awakening?
There are also different types of Moksha, apparently (meaning from the point of view of ignorance), such as jivanmukti and videhamukti and numerous other classifications in the scriptures. But in essence we don’t have to worry about these as this is just more book knowledge. The scriptures and sages (such as Ramana) remind us that this is really more ignorance for the mind. Instead, keep it simple and just keep on with your basic Sadhana:
1. Be still (raja yoga)
2. Know who you are (jnana yoga)
3. Adore your God-Guru-Self (bhakti yoga)
4. Give thanks for all that comes your way (karma yoga)
Note – all of the above leads to a peaceful open indestructible stillness (Mouna or Atman/Brahman)
5. Dissolve into Divine Love (Moksha/Advaita/Bhakti/Jnana)
