“The essence of Tantra is purification of the Five Elements, to awaken the Kundalini Shakti, which is your own personal shakti (power, energy). Any spiritual practice, in any religion, is basically some process or other of awakening Kundalini, and Kundalini can only be awakened once the Elements in your body have become purified. Do you understand?”
Earth, Water, Fire, Air, Ether
Understand that these five elements are not as those of the periodic table; the elements in the periodic table all contain these five elements, as does everything in existence, including your bodies, gross and subtle. Consciousness, through the power of focused awareness (will) and intention (intensity of involvement), can manipulate and control these elemental properties.
Earth governs the stable, the physical, that which takes solid form in the body. Its origin is Muladhara. When you are too earthy, you will feel tired, lethargic, and drained. When you are lacking earth, you will feel agitated, restless, and insecure. When you are balanced in earth, you will feel relaxed and at ease.
Water governs the flowing, the emotions, that which is liquid in the body. Its origin is Svadhisthana. When you are too watery, you will feel overly emotional and hyper-sensitive. When you are lacking water, you will feel an inability to relate, dry, and lacking sweetness. When you are balanced in water, you will feel empathic and relatable.
Fire governs the transformative, the burning, the drives, that which is energetic in the body. Its origin is Manipura. When you are too fiery, you will feel prone to outbursts and extremes of passion and temper. When you are lacking fire, you will feel dull, without ambition, and apathetic. When you are balanced in fire, you will feel a strong and consistent drive, passion, and zest for life.
Air governs the imbuing, the swift, the breath, that which fills and moves in the body. Its origin is Anahata. When you are too airy, you will feel mentally cloudy or distracted and unable to focus. When you are lacking air, you will feel mentally unable to perform and dull. When you are balanced in air, you will have a clarity and sharpness of mind that is also relaxed and without undulation.
Ether governs the expansive, the spacious, the supportive, that which is void and fundamentally present in the body. Its origin is Vishuddha. When you are too etheric, you will feel dis-associative and unable to relate with mundane existence. When you are lacking ether, you will feel disconnected and lost in your perspective. When you are balanced in ether, you will feel calm, clear, relaxed, connected and content.
These Five Elements change in our bodies throughout the day due to our natural rhythm, outside influences, and as a result of our own thoughts, emotions, and actions. However, since these states of experience are internal states connected to our inner system of function, if we go to the root of that system, we can adjust the levels of these Elements in order to induce an immediate change in our internal state.
In other words, if I understand how to directly influence my nervous system, then I can adjust my internal state at will, and no longer will the outside world dictate my internal state, and I will be a master over myself; the king will have returned to rule in dominion over his kingdom.
Remember that where and how intently I place my awareness influences these Five Elements. Focusing in Muladhara brings more Earth, Svadhisthana more Water, and so on. The keys the kingdom are within our grasp; it is up to us to take back control and learn the purification and dissolution of the elements, the ultimate tantra.
