Ego is not against Spirit as in a battle between good and evil. Ego is the fictional creation of Spirit which allows for the perception of distinct forms – the foundation of experience in this material dimension.
Only through buying into Ego’s assertion that thoughts are true does one resist Spirit’s directive to uplift and expand energy of awareness. This ‘buying in’ is ignorance – not right nor wrong – just a mindset that generates the experience of struggle.
There is nothing to do but remember the Truth that there is no truth to any thought. From there, Spirit is allowed to uplift energy of awareness to lighter frequencies of mind – and infinitely more expansive Joy/Peace/Love/Pleasure may be experienced thereby.
