In my personal experience (with experiencing life naturally from these realisations to a fair extent over many years, then in recent years with the Self-Realisation audio series itself), they are also an energetic realisation and energetic states of being.
The Self-Realisation audios affect my entire energetic being and ego quite strongly, in addition to internal mental representations. The effects I’ve experienced feel similar to the effects on the energy body and ego from Ego Dissolution and the Vibration series.
Each person’s experiences vary individually, but as our energy body and ego are intertwined with any realisations and internal mental representations, I think effects on one’s entire energetic being might be possible for everyone to experience over time from this series. Perhaps there are always some subtle effects on one’s entire energetic being from this series and it certainly helps dissolve one’s ego.
So it’s certainly possible the Self-Realisation series might boost your results from other fields, depending upon your experience, from that perspective!
