"Universality is not an idea; it is an existential truth. It is individuality that is an idea. Yoga is simply chitta vritti nirodha. That means, if the activity of your mind ceases and you are still alert, you are in yoga."
Religions and eastern traditions have a few things in common, and one of them is the concept of universality, unity, or Yoga.
In Islam for example, Tawheed, is at the core of the Quran. Tawheed literally means unity, and according to the Sufi tradition, Tawheed is another word for universality, unity or oneness.
In christianity, the bible says: For in one Spirit we were all baptized into one body—Jews or Greeks, slaves or free—and all were made to drink of one Spirit.
This reality of universality is pretty straight forward, it's a reality where everything is connected and considered a part of the one whole. So everything around us, including us, is simply a manifestation of this one unifying energy or consciousness.
In our case as humans, we're born with egos, and the ego acts as a veil that shields us from this unified reality (to transcend the veil is awakening or enlightenment).
When mind activity comes to a stop, we see past the veil, and we experience reality as it truly is, unfiltered and beyond the ego. Here, we find ourselves in Yoga, Yoga meaning universality or union, a union where we become one with the environment around us. In this state, the idea of individuality, or separateness, ceases to exist, and we understand and feel the unity of being. We simply realize our natural state or essence, which is beyond the bodymind, and unbound by space and time.
This teaching is at the core of Yoga, Zen, Sufism, Taoism and the list goes on.
