1. Beliefs are formed by either (a) or (b).
Beliefs do not create reality in (a).
Your argument appears to rely heavily upon the veracity of these statements.
Do you firmly believe them to be true?
If so, have you noticed how this does naught more, than provide further evidentiary support for the philosophy under discussion?
In my opinion, intellectual debate on this particular philosophy, whilst quite entertaining, tends to be self defeating.
A way (perhaps the only way) of testing for veracity, is via practical experiment.
=============================================================
For those interested, a couple of publications, offering a useful blend of theory and practical exercises, that one might consider for further exploration are:
"Three Magic Words" by U.S. Andersen,
"Concentration" by Mouni Sadhu,
the former publication, by Andersen, serves as a gentler introduction for those with no prior experience of metaphysical concepts.
The latter, by Sadhu, whilst it also serves as a useful introduction, incorporates a series of concentration exercises demanding a far greater level of mental endurance.
Ardent secularists will likely find the material in aforesaid publications confronting, as certain contemporary secular conceptions, are dismissed as misconceptions, by both authors.
Now, one may rightly ask, how can this relate to trading?
It needn't necessarily relate, but it can be related, if one so chooses.
Upon being confronted with failure in any aspect of life, and seeking remedy for same, it can be quite helpful to have an understanding of the underlying mechanics.
"Something always goes wrong","I am not good enough","I never catch a break","@#%& happens","This always happens to me","SNAFU","Life is hard","I never win anything","Trading is hard"
All of the above can be expressions of belief. All of them can be, or become, true.
But they need not necessarily be, nor become!
With greater self awareness comes greater power to shape one's life experience.
So, whenever performing post mortems on failed strategies, it can sometimes pay to consider major contributing factors.
One's personal religion (i.e. entrenched belief system) is a major contributing factor which can manifest success or failure in a variety of ways. (Even supposedly external events, of a seemingly happenstance nature, could potentially be a direct consequence of personal belief.)
Every consciousness, every day, is exercising a "god" like power, and continuously manifesting miracles (these have been occuring so commonly, for so long, that they are typically viewed as banal).
So what miracles has one been manifesting? Are these the miracles one wants? If not look to the underlying belief and change it!
