Paul Rogers94 said:Sure, it’s a bit muddled and unclear like this. You could list another hundred types of yoga if you wanted to, but an experienced devotee can see there are really just two fundamental paths or currents. I’ll just mention them now—and I might elaborate more later if I feel like it and decide it’s actually worth the effort, since this topic is the starting point for my Magnum Opus. They are:
Let’s call it Willful Yoga (which works with Prana and Kundalini): it stems from the idea that mental content is cluttered by sensory impressions. To control the mind, you have to control the senses, and vice versa. The foundation is sublimation (not suppression) of sexual energy (Virya) into mental energy (Ojas Shakti)—we raise the Kundalini to the Sahasrara, resulting in Nirvikalpa Samadhi. This requires breath control, dietary control, sleep control, and mastery over all other aspects of life. An adept of this path masters all levels of existence (Lokas), entering and exiting them at will...
And let’s say Sahaja yoga (so-called Natural Yoga, or the yoga of direct insight into the true nature of reality—meaning without the mediation of the senses or the mind). Much like Zen, it allows things (life) to simply happen without any willful interference. Every attempt at intervention is just an obstruction. You have no control over experiences, nor do you cling to them, just as you don't cling to anything else. This current has its own completely different dynamic, and the result is direct insight into the true nature of reality (Jnana). It is the most beautiful and miraculous path—pure bliss through non-attachment and devotion. It doesn't bargain; it doesn't demand you do "this" or "that" to get something. It is unconditional. It doesn't ask you to earn THAT, because you *are* THAT (Tat Tvam Asi)...
These are the only two ways to wake up from all the dreams.
Only by understanding these two currents can we make sense of everything else.
Everything else listed is merely a consequence of one current or the other. There is no third option.
I should note that this is just a very, very rough outline, as I am in no mood for any serious elaboration—especially not here, because that would be pointless.
So, basically, Raya yoga and jñāna yoga are the two big branches. Though, I gotta say, that sentence of yours is a bit of a contradiction:
"
yoga of direct insight into the true nature of reality—without the interference of the senses or the mind"—I mean, how are you supposed to realize what is true or not without using your mind or your senses in the first place?
There aren't books written about this second type of yoga because it’s impossible to write anything coherent about it.
That being said, I think those two yogas you mentioned actually bleed into one another; you really need both. Also, you totally overlooked bhakti yoga and mantra yoga, which are vital (sometimes even essential) for moving forward, whether you like it or not.
Like Patanjali roughly says:
..by
chanting sacred texts, one establishes a connection with their chosen deity...(bhakti yoga)
....
through the repetition of pranava, God is revealed(mantra yoga)....
