The reason we see certain numbers, colours, clothes, actions etc as lucky for us is due to the “history” of having experienced a certain energy of success, luck, joy etc upon previously experiencing that number, colour, shirt etc.
What we are really doing is trying to ignite the same resonance by using the same tools (ie number, colour, shirt) to create another situation of success – a reality of success, joy, ease, happiness.
Truthfully, of course your lucky number, shirt, colour, action can work, by aiding you to recreate the resonance needed for a circumstance to occur
but. . .
that resonance could actually be created from within and it is the resonance which results in the desired creation not the lucky object, number, colour etc.
