What if Yoga itself is an illusion ? Maybe, it was created to understand other illusions. The final stage of Yoga, Samadhi, can be another kind of cosmic manifestation. A manifestation where time is not linear. After reaching Samadhi, one can feel non-linearity of time. We can have experience beyond space-time but experience beyond space-time can be some kind of matrix, some kind of an illusion.
And we can’t deny this possibility. We are just plunging from one illusion to another and will never know the absolute reality. In conclusion, Yoga doesn’t ensure us that we are going to know the absolute reality but surely it leads us to amazing possibilities that will enrich our experience.
