The measure and duration of our life force energy as it manifests in this 3rd dimensional, substance reality is defined as Tonal orende. In humans, tonal orende is calculated based on five different aspects: emotional, physical, mental, spiritual, and sexual.
To get an idea of the meaning of tonal orende in practice, consider these reflections:
How much mental stimulation do you require in a day? How many times per day are you prompted to read a book or increase your mental knowledge in some way? Here, the more stimulation required the higher the mental orende.
