According to Shakta Tantric doctrine, Muladhara(base chakra) is the place where kundalini-a latent cosmic energy- resides in every living human being. When this latent power is activated through Hata yoga practices(pranayama, purification of the nadis, and so on), it rises through each of the spinal chakras in tur and up through the top of the head, to the Sahasrar/Crown Chakra, or “Thousand-petalled Lotus,” above. There it unites with its opposite polarity, the Paramashiva or Supreme Godhead Consciousness, and the yogi attains total liberation from everyday reality. Put more simply, kundalini is the feminine Shakti power of the eternal goddess, who wants to unite with her Lord Shiva at your Crown Chakra.
Kundalini Energy and the Nadis
Kundalini energy can be awakened through a combination of Hatha yoga postures, bandhas (body locks), pranayama (correct breathing), mudras (hand gestures), mantra chanting, meditation, and visualization techniques. During this process our latent kundalini energy works with the nervous system to achieve a profoundly new level of consciousness.
This dormant energy rises through the nadis. According to an ancient Tantric text, there are 14 main nadis. The three most important are the ida, pingala and sushumna nadis. The Base Chakra is where all three meet. From Muladhara, the subtle energy from ida and pingala ascends, alternating at each chakra. If kundalini flows through sushumna to its full destination, soul realization is consciously achieved.
Awakening Kundalini Energy
The key processes for awakening kundalini energy are purifying mind and body. Purifying the body eliminates accumulated toxins, and whatever purifies the body will also purify the mind. According to Ayurvedic medicine, fasting is one of the most effective methods of detoxing the body. Other methods include pranayama and bodily cleansing.
