Inertia is a natural state of energy. In Sanskrit, they use the term Tamas. When in motion, it is known as Rajas. But they also have a third state known as Sattva, generally translated as purity. This is similar to Tamas in the sense of being more still but is it’s the opposite in quality. Where Tamas is resistance, Sattva is peace.
When we face inertia in our lives, it is usually due to change. The shifting of a state from still to moving. We may often experience change with resistance, emotionally as fear.
Fear does not have to mean no. Just caution. Is this the step we want to take? Then just be OK with what arises. Let fear be there if it comes, then it will pass. And do it.
Rajas will then arise to transform and ideally settle into sattva. However, we will soon find sattva may have degraded, becoming tamas. (lack of sleep, for example) Change is then necessary to transform it again.
If we are able to connect internally with our true nature, the energy will degrade into tamas less and less. Inertia will become less of an issue. However, the purer we get, the more inclined deeper inertia will come to the surface for its transformation. That process may make it seem like a never-ending series. But the difference is that now we’re rebuilding the whole environment, not just maintaining it. The profound benefits of that will soon become apparent.
