I’m wondering if it is kosher to mix practice of kundalini yoga with Orthodox Judaism?
Kundalini is the most spiritually intense form of yoga. Most other forms of yoga are primarily forms of exercise. Kundalini yoga is a spiritual practice. Is it kosher for Jews to do it?
I used Rabbi Google and I couldn’t find any warnings that Kundalini Yoga was forbidden to Jews.
I found this essay on Jewish sexual healing:
A Jew’s job is to reveal Hashem everywhere, even in sexuality! This is why a bris exposes the "crown" of the sexual organ and why in heaven it says that the crowns [are] in the heads". We sublimate sexuality into us and expose Hashem even there. We don’t squash or harness and circulate it. We sublimate it. We transform it into Divinity.
This Jewish idea of sublimating sexuality is a major difference between the Jewish view and the rest of the world. Kundalini and the Daoists, through their sophisticated techniques such as tantric yoga and Daoist sexual practices, bring sexuality into their consciousness, and according to Judaism this generates impure, evil energy. The Jewish method brings Divine Consciousness into our sexuality!
We view sexuality not as a tool to energize us, but rather as a holy gift which can connect us to Hashem in the most sublime and holy way.
They see sex as a body power to be tapped; we see it as the most sublime window to G-dliness! Through the act of sexual relations, a man and wife, together with Hashem, create another human being. This is the closest way for a human to emulate Hashem, for only Hashem can create something from nothing. Hashem has given a man and wife a chance to create.
In Judaism what is the connection between sexuality, vibrancy and healing? Yes. We do see sexuality as a power if it is strictly followed within the parameters of halacha. This is called "Tikkun habris." A person who is tahor (pure) and kadosh (holy) is not only able to have lower bodily pleasure but he is also able to have higher connections to spirituality, infinity, and much higher connections to Hashem (this heightened connection is fundamental to Jewish healing, where the healer is connecting to Hashem to help guide the patient and help the patient connect to Hashem).
