There are those, myself included, who say if you are "trying" or making an effort to meditation, that is not meditation. Meditation is without effort. It's like the story I heard of the Buddhist monk who said to his master, "Master, I practice meditation constantly." And the Master responded, "That's good. One day soon you can quit practicing it and start actually meditating".
The "effort" in mediation is to make no effort. If you are making an effort, you aren't meditating. It's that simple.
You should read the link I shared. There some good information in there I think may help you with your confusion about these areas. Let me highlight the Casual states for you, which are for all intents and purposes effortless states.
THE CAUSAL LEVEL
Q: That’s very clear. So what about the next level, the causal?
A: You’re sitting there, just witnessing everything that arises in the mind, or in your present experience. You are trying to witness, equally, all the dots on the wall of your awareness. If you become proficient at this, eventually rational and existential dots die down, and psychic dots start to come into focus. Then, after a while, you get better at witnessing, so subtler objects or dots start to show up. These include lights and audible illuminations and subtle Deity forms and so on. If you continue simply witnessing—which helps you disidentify from lower and grosser forms, and become aware of the higher and subtler forms—even subtle objects or subtle dots themselves cease to arise. You enter a profound state of nonmanifestation, which is experienced like, say, an autumn night with a full moon. There is an eerie and beautiful numinosity to it all, but it’s a “silent” or “black” numinosity. You can’t really see anything except a kind of silvery fullness, filling all space. But because you’re not actually seeing any particular object, it is also a type of Radical Emptiness. As Zen says, “stop the sound of that stream.” This is variously known as shunyata, as the Cloud of Unknowing, Divine Ignorance, Radical Mystery, nirguna (“unqualifiable”) Brahman, and so on. Brilliant formlessness, with no objects detracting from it.
It becomes obvious that you are absolutely one with this Fullness, which transcends all worlds and all planes and all time and all history. You are perfectly full, and therefore you are perfectly empty. “It is all things and it is no things,” said the Christian mystic Boethius. Awe gives way to certainty. That’s who you are, prior to all manifestation, prior to all worlds. In other words, it is seeing who or what you are timelessly, formlessly.
That’s an example of the causal level; that’s jnana samadhi, nirvikalpa samadhi, and so on. The soul, or separate-self sense, disappears, and God or separate Deity form disappears, because both—soul and God—collapse into formless Godhead. Both soul and God disappear into the Supreme Identity.
There's a lot more there for you to glean good information from. I recommend spending some time reading it.
