What is Kundalini?

 What is Kundalini. Translated from Sanskrit to "coiled serpent," it describes the energy that rests, often dormant, coiled at the base of the spine. When it rises or awakens, it can cause a range of experiences and symptoms. Kundalini is considered life force energy, meaning it is the main source of inner power. We all have it, but not all of us have experienced it as "awakening." Everything you are, think, remember, that you can visualize - everything - is your consciousness - This is Kundalini.

This energy, traditionally considered feminine (sometimes called Kundalini Shakti), is only able to flow freely when the chakras are completely clean and open. The chakras are like gateways to dimensions of perception. For many, blocked chakras do not allow Kundalini energy to flow.
What causes the awakening of awakening?
The truth is that there is no single answer to this question. For some, Kundalini awakening can occur after years of cultivating spiritual practice. Doing Snake yoga , meditation, etc. But equally well, it can happen spontaneously, without prior training.
Kundalini growth is an automatic phenomenon - and can happen within any type of spiritual discipline, in any style of yoga. So it's not something you should necessarily look for.
Through the practice of enriching your spirituality and inner world, you can eventually become so neutral and balanced that you know you have reached a place of total awakening. 

What is Kundalini?

The difference between Snake awakening and spiritual awakening can be difficult to discern in the moment. It is not always possible to know if our energy is increasing or if we are going through a different kind of spiritual experience. We may have instances of Snake awakening, and then we may also have instances of the upper chakras opening. They don't have to be related, but they can be.
Opening of the upper chakras can manifest as sudden realizations, visions, insights, connecting with spirits, psychic insights, experiences of sudden feelings of love out of nowhere and more - but that doesn't necessarily mean it's the Snake.
Simply put, awakening can be classified as a type of spiritual awakening , but spiritual awakening is not always related to Kundalini.
If you are not sure what you are experiencing, the best method would be to seek the guidance of a spiritual teacher or guide.
