How can one recover the ability, the will and the joie de vivre?
You have to start by asking yourself why you are depressed, what triggered the depression within you, and it is usually the failure of your expectations, your delusions.
The moment we have expectations we risk having delusions: the more plans we make, the more we want, and the more we are at risk of being disappointed, and as a consequence we become depressed.
Depression can have its positive side, that of making us go deeper into ourselves, as the depressed person alienates himself from the outside ( he is not interested in it and sees it as a threat from which he must defend himself) therefore his attention is focused on himself to find the means of getting over the depression.
Obviously it always appears as emotionally motivated, but it has physical repercussions, so there is a physicality, a chemical element that cause one’s mood to change.
To get over this, one needs to act considering two aspects: the chemical and the emotional.
You must also understand however, that delusions are the daily bread of Life, and the reason why people become depressed is because they do not understand that delusions can also be a teaching that Life is offering us, so that we can reflect without living it as an insult or an offense, or something that shouldn’t have happened.
All this makes the human being depressed, and the individual loses his self esteem and the zest for life.
To return to the awareness of this mechanism, of being a cell that is part of the Whole, helps greatly in getting over depression, because if I am a cell of the Whole, I can benefit from all that the Whole can give me, just like a cell of a body does not need to find oxygen or blood for itself because it is the body that gives the cell everything it needs; at the same time one lives Life with relativity, because if that situation has not met my expectations, evidently that was not the result that was right for me.
Humility is needed to feel oneself as a cell of the Whole, otherwise if I see myself just as a personality, every insult I receive from life is devastating; if on the other hand, I feel myself as a cell that flows in the Whole and understand that the scope of my life is to help evolution, then my purpose must simply be to do my best in everything that Life offers me.
If I act in this way, I give the right information to my energy, and in so doing, I help evolution.
