Shakti Kundalini:

"There is only one energy (Shakti) that keeps taking on new shapes and forms. Each time the energy takes on a new form, we give it a new name."
One energy with many names and forms: There is one energy that keeps taking on new shapes and forms. In Tantra the name of that energy is Shakti, which is the manifesting, or the sacred feminine force that is actually one and the same with its only apparent companion Shiva, the latent, or masculine. Each time the energy takes on a new form, we give it a new name. Shakti becomes Kundalini Shakti, or simply Kundalini. Kundalini becomes the energy of Prana, which flows in patterns or channels called Nadis, and concentrates itself by forming intersections known as Chakras. The subtle energies condense and become known as earth, water, fire, air, and space, forming our experience of the gross world. Kundalini Awakening is the awakening of the primal energy or Shakti in its true form.
Seek to experience that one energy: To know, in direct experience, that unchanging truth, the one energy that is the substratum of all of the names and forms, is one of the ways of describing the universal goal of spiritual life. It is the experience of the union of Shakti and Shiva, creation and its ground, feminine and masculine, even though they were never actually divided in the first place. It is like wetness that is never separate from water, sweetness that is never separate from sugar, and warmth that is never separate from sunlight.
We also rename the energy of consciousness: In a similar way, there is one energy (Shakti) in the universe that also keeps changing its form. Each time that that energy changes form, we give it a new name. Following is a description of how this works. In reflecting on this, it is important to keep in mind that some schools, teachers, or lineages use the various terminologies somewhat differently from one another, though the principles might be essentially the same. It is the process that we want to clearly understand, so that we may journey through these levels to their source.
Shakti: The universal energy of consciousness is called Shakti.
Kundalini-Shakti: The word kunda means a bowl in which fire is burned. Thus, when Shakti resides in a bowl called kunda at the base of the spine, it is called Kundalini-Shakti.
Kundalini: Then, in our common language, the word Shakti is dropped away, and the energy in the bowl is simply called Kundalini.
Prana: A small unit of the energy called Kundalini radiates off of its subtle mass, like steam rising from a bowl of boiling water. That radiating energy is called Prana. Again, once it changes form slightly, it gets a new name. Just like the water turning to steam, while still remaining water, the Kundalini, which is still Shakti, "becomes" Prana.
Nadis: That Prana tends to flow in certain patterns, or lines, like the steam rising in more or less predictable channels. These lines, patterns, or channels are called Nadis. Once again, a new name is introduced.
Chakras, marmas: The thousands of Nadis, with their Prana (that is really both a small amount of Kundalini, and still Shakti), crisscross here and there like minor or major highway intersections. Those major highway intersections are called Chakras (minor intersections are Marmas or Marmashtanas). It is because of this crossing pattern, like highway intersections, or spokes on a wheel, that the word chakra is used, which literally translates as wheel.
Vayus: From there the Chakras, with their different shapes and styles of intersection, cause five basic flows of energy called Vayus based on their specific functions.
Bhutas, tattvas: These take on the qualities of earth, water, fire, air, and space, which are called Tanmatras and Bhutas at their subtle and gross levels.
Indriyas: Also from the subtle energy emerge the five Jnanendriyas or cognitive senses of smelling, tasting, seeing, touching, and hearing, as well as the Karmendriyas or instruments of action of eliminating, replicating, moving, holding, and communicating.
Brain, body, breath: Collectively these manifest as the various aspects of our physical brain, body, and breath. Still, they are none other than the Shakti, Kundalini-Shakti, Kundalini, and Prana flowing in Nadis, which they were all along.
There is only one energy: One of the major insights of Tantra and Yoga, possibly the key to the whole science of Tantra, is that there is only one energy in the whole of the universe, and our task is to know that, in direct experience.
Experiencing that one energy: With Kundalini Awakening, the full force of the dormant Kundalini comes forth from its dormant state. To awaken the Kundalini and allow it to rise through the levels of manifestation, returning to its source, is the ultimate Realization of the Absolute, which is both mother and father aspects of reality, Shakti and Shiva. Through self effort in Tantra and Yoga, and the bestowing of grace, or Shaktipat, the sincere aspirant experiences this Truth.This site is devoted to presenting the ancient Self-Realization path of the authentic living Traditions of the world in simple, understandable and beneficial ways, while not compromising quality or depth. The goal of our sadhana or practices is the highest Joy that comes from the Realization in direct experience of the center of consciousness, the Self, the Atman or Purusha, which is one and the same with the Absolute Reality. This Self-Realization comes through practice of any of the various Paths. We employ the classical approaches of Raja-Yoga, using Jnana, Karma, and Bhakti Yoga, as well as it's various aspects Hatha, Kriya, Kundalini, Laya, Mantra, Nada, Siddha, Tao, and Tantra Yoga. Meditation, contemplation, mantra and prayer finally converge into a unified force directed towards the final stage, piercing the pearl of wisdom called bindu, leading to the Absolute.
