Kundalini is commonly said to be a coiled serpent - snake of immense power resting - asleep - torpid in the bowl at the base of the spine. Is she really there and Why is She coiled, or should I ask is she really coiled and why is she resting, or is this all a diluted myth that has flowed down the river of time from her true origin where realized knowledge was the reality?
Is she really there and Why is She coiled, or should I ask is she really coiled and why is she resting ?
No , Kundalini as energy is not a Myth. The energy is there. This fact is advocated by multiple Hinduism scriptures which are describing Kundalini Shakti and how to awaken her in order to get the liberation or Moksha.
The Kundalini shakti resides in our subtle body and remains there always, but part of her divine energy is in our physical body which is also called as the gross body and manifested as Prana, Apana, Vyana, Samana and Udana.
Shandilya Upanishad of Atharvaveda - Chapter I -Tells us that this Kundalini shakti is one of the forms of eight Prakritis.
As a spider flies to and fro within a web of fine threads, so prāṇa moves about here. In this body, the jīva rides upon prāṇa. Lying in the middle of the navel and above it, is the seat of kundalinī. The kundalinī śakti is of the form of eight prakṛtis (matter) and coils itself eight ways or (times). The movement of vāyus (vital airs) checks duly the food and drink all round by the side of skandha.2 It closes by its head (the opening of) the brahmarandhra, and during the time of (the practice of) yoga is awakened by the fire (in the apāna); then it shines with great brilliancy in the ākāś of the heart in the shape of wisdom
The Yoga-Kundalini Upanishad - Chapter 1 - Verse 82 - also confirms the above.
शक्ति: कुण्डलिनि नाम बिसतन्तुनिभा शुभा |
मूलकन्दं फणाग्रेण दृष्ट्वा कमलकन्दवत् || 1.82||
The Sakti named Kundalini, which is like a thread in the lotus and is resplendent, is biting with the upper end of its hood (namely, mouth) at the root of the lotus the Mulakanda
Kundalini Power is said to be a Goddess a Shakti as creator and sustainer of the universe . The Hatha Yoga Pradipika is the authoritative book which talks about Kundalini . It is said in the book that " The Kundalini is sleeping, closing the door of the Sushumna. She sleeps above the Kanda or where the Nadis unite. She gives liberation to the Yogi and bondage to fools. He who knows her knows Yoga."
तस्मात्सर्व-परयत्नेन परबोधयितुमीश्वरीम |
बरह्म-दवार-मुखे सुप्तां मुद्राभ्यासं समाछरेत || 5 ||
tasmātsarva-prayatnena prabodhayitumīśvarīm |
brahma-dvāra-mukhe suptāṃ mudrābhyāsaṃ samācharet || 5 ||
In order, therefore, to awaken this goddess, who is sleeping at the entrance of Brahma Dwāra (the great door), mudrās should be practised well.
Why is Kundalini resting ?
The answer is provided in the book - Kundalini, The Mother of the Universe, by Rishi Singh Gherwal
As describe by author Kundalini as divine static energy is sleeping at Muladhara Chakra and Dynamic enery of Kundalini flows all over the body.
P.22 The Kundalini is Divine static and dynamic energy. The static energy (Kundalini), is sleeping at the Muladhara (Root Chakra); the dynamic energy of the Kundalini is all over the body as Prana, Apana, Samana, Vyana, and Udana. These five Vital breaths, or life forces, keep the body together. The duties of the five Pranas are as follows: Prana remains in the upper part of the body, and always moves upward; the Apana resides in the lower part of the body, or abdomen, and always flows downward; the Samana stays in the first section of the torso, digesting and distributing the food substances; the Vyana resides in the heart, and from there moves all over the body, its duty being the circulation of the blood; the Udana carries the Soul upward when the body dies.
