"Kundalini Maha-Yoga is a self-proven and self-perfecting spiritual practice. The power of Kundalini can cause an initiate to perform kriyas (automatic movements) through the power of Kundalini itself. The force of the Kundalini is such that the body performs these asanas unconsciously. Another name is Siddha-yoga, or the self-proven path of meditation. In all aspects, body, mind and intellect, Shakti uses Kundalini to perform the meditation. The initiate is drawn into flowing with the energy and must surrender to the process. When and how Kundalini-Shakti manifests is the work of the divine power (Shakti) Itself. To practice Siddha Yoga one must allow the divine power the opportunity to perform the meditation and yogic postures without interference.
Traditionally, it is believed that without initiation it is difficult to realize the fruits of knowledge, meditation, yoga, japa (chanting), tapa (austerities), devotion, karma, and dharma (religious duties). Kundalini Maha-Yoga (Shaktipat) as a path of initiation is different from other paths of meditation and/or initiation, because on other paths one has to learn certain tasks or master specific techniques. Practitioners are responsible for doing meditation or they may have to learn about different stages in meditation. Ceremonies may have to be performed or different yogic postures or asanas assumed, or they may have to struggle to eject undesirable thoughts from their mind.
In Shaktipat it is not necessary to do any of these things. All the person has to do is sit with a complete sense of surrender to the present moment and experience. To achieve Shaktipat a person should be warm and welcoming to all thoughts or emotions as they occur, allowing inner life to flow effortlessly through the body without interference or judgement. Then, according to the nature and state of the spiritual consciousness of each initiate, different meditative experiences — emotional, intellectual, or creative in nature — will occur by themselves."
