Not necessarily. You can press a saw against a piece of wood or you can press a piece of wood against a saw and move either respectively. The results will be the same -- a cut piece of wood. Those are two different, opposing methods that have the same outcome. Then, you can use a blunt table knife instead of a saw. That's an incomplete way of doing this particular task.

When I said that Gnosticism and Kabbalah are incomplete, I meant the latter. Kabbalah was always incomplete as that path stops at nothingness of formless realm (to use Buddhists parlance) and mystical union is still a sort of taboo and not a generally accepted tenet.

When it comes to Gnosticism, it was in 1-2 century CE already in a state where no Gnostic had a clue about the nature of actual gnosis. Whether that was always the case, I don't know.

However, if so, it's something that happened to Vedic Hinduism and Judaism as well, and what Jesus and Siddhartha presumably set out to set straight. Only to suffer the same fate -- during the centuries that became millennia, their explanations became equally twisted, misunderstood, and misinterpreted, and those erroneous interpretations became de facto creeds of their respective traditions. Hence the flawed nature of those other traditions I've mentioned.
