Stablising the four elements

In Buddhism, we sometimes talk about practice in regards to the four elements earth, water, fire and air and occasionally we speak of space and consciousness elements.
Earth is the element of density, thoughts, and feeling that feels heavy, depression could be thought of as having been affected by the earth element. The weight of the body and bones is an obvious earth experience, we are often directed to the body to help ground us so we don't get carried away with certain thoughts and feelings. The Buddha asked the earth to witness and aid him seeing clearly the effects of Mara.
Water gives shape to things, as again with the bodily shapes are very much dependent on the fluids held inside by the skin. The shape of the body changes as the fluids drain away and dry up. Thoughts can be fluid in their ability to constantly change form, moving from one theme to another.
Fire gives us warmth and coolness, we can experience this by observing our body temperature and the bodies contact with the weather. We may notice in thoughts of anger, rage or aversion.
Air is movement, the flow of blood, the vibration of the breath, the movement of the body, the chatter of our thoughts.
Depending on how we pay attention to things depends on how in balance these elements are. This is how samadhi matures. As we gently pay attention to our experience the sense of gentleness/care and permission allows the elements to find balance. As the elements begin to settle we begin to become aware of the element of space and consciousness. Now that space is emerging it gives consciousness the ability to develop insight into the dynamics of the four elements earth, water, fire, and air. As space becomes more dominant we begin to feel equanimous not so caught up in the play and drama of earth, water, fire, and air.
Space begins to give a sense of being infinite, vast, everything seems to be within you. With this the sense of consciousness to seems to become infinite and vast, as a sense of being the one who knows arises. This arises with taking the elemental experience personally, as mine. When this sense of self-falls away when consciousness rests into itself, knowing nothing, unaware of itself. With the reappearing of selfing process after this, the ability to perceive the perception of nothingness, this is in relation to the loss of self and is dependent upon consciousness having rested into its self, as we become familiar with this perception it opens up into the sense of neither perceiving or not perceiving. A deep sense of not knowing balanced with equanimity, this aids release of subtle views.
When the elemental play is cleaned of the ignorance of self-ing the experience, it flows as it is:)
