My dear Joel,
I would like to say to your question that you should aim your mind to bodhicitta, in this life as much as possible. In order for that, then shi-nä is ok, but do not think that shi-nä is the main one, the main plan, which is to achieve enlightenment for sentient beings.
Anyway, I checked your question and to be a translator is good; it’s not the best, but it is good. Shi-nä doesn’t come out.
Anyway we have shi-nä realization numberless times. We have been born in form and formless realms numberless times. Even Hindus have the method to achieve shi-nä, to achieve the full characteristics, so it’s nothing special for Buddhists.
At the moment shi-nä doesn’t come out for you.
With much love and prayers...
