Something I pick up in your message Raul, is that you are taking the end goal of 'existing without energy' as something that should be here right now and because you see that this is not the case, connecting this to 'the message of/as Desteni' and doubting the whole message. So what I see, is that there is a realness in what you write and experience and an excuse as well.
The realness is that we indeed will not be able to in one moment, will be motivated without any energy anymore and things that we like. This because our mcs is integrated within our physical body and so it is a process to walk through all the layers and bring the energy back and redefine into a physical/self-expression.
The excuse in it is the questioning of the process and message of Desteni as a whole; which is an excuse, or let's say 'trick' from who we are in/as the mind, to then 'not even start' the whole process because 'does it mean anything' to do so?
Practically, what I have done for myself, is once that I have seen for myself in self-honesty that the message (Desteni) as a whole contains all and everything and so, I made the decision to 'take on' the whole message and All aspects of it as 'real' - this was the start of my Desteni I Process 7 years ago. However this doesnot mean that I can now in one moment, embrace all and everything in it. We have all many points to walk through and so, this takes time. For example, 7 years ago I felt like my world collapsing when a partner would not be in my life anymore, like 'it doesnot make any sense anymore' as my whole life would not make sense. Knowing ofcourse that this is not real, but experiencing it as such. So I started walking this and wrote about it many blogs and lessons and timelines and after 5 years, needed to walk the whole thing in physical reality and 2 years later, coming again on the same point without the partner, now more stable in it - where I noticed I had build a foundation within myself as something worthwhile to build my life on - but still experiencing the same energies releasing of 'it doesnot make sense anymore' etc. What I mean by this example is that if I would have forced myself to in one time 'let go of everything' I would have go into a striong resistance and not even started, because it is not realistic to approach it as such.
Practical I would say that you can use for example your guitar playing to see how it motivates you, what it gives, what you can express in it, how you can redefine it into a living expression, something that you can stand within and as, so explore the energies coming up while walking what you like and focus on considering as much aspects/dimensions as you are able to in that moment (I mean so that you will consider the effect on yourself and others within a starting-point of what is best for self/all).
And while doing so - as how is mentioned in other comments and how I describe here above of where and how I did this - there is a decision needed of what you want to walk in this life.
With regards to your wondering if Bernard would sing and how it would sound etc; I find the music and voice of Cerise (and especially 'Fire' as my favorite
) a great example (and perhaps for the singers under us, an inspiration) of the depth and what and how music can be of support to process and to 'what is best for all'. Her voice is touching 'me' deepy within. But can look out for other mucisions as well who have this for you, within Desteni and also in general and on what level etc.
