It seems to me that the understanding of the terms "
gurmukh" and "
manmukh" have been somewhat misinterpreted.
First, let us start with the term "
gurmukh".
"
Gur" refers to "guru". "
Mukh" refers to will.

Whilst many have regarded the "
gur" of "
gurmukh" to be a reference to the discrete Guru (i.e. the ten human Gurus and the eleventh perpetual Guru, the Granth Sahib), my personal interpretations of the wirtings of
gurbani have lead me to believe that the "
gur" of "
gurmukh" is, in fact, a reference to
satgur (True Guru) or
waheguru.

Therefore, to live under "
gurmukh" means
to overcome the ego of believing that you have any real control over your life and to submit to the will of the Universe.
This doesn't necessarily mean that one should become
amridhari (although if someone feels that this is their personal destiny, then they should not feel opposed to embracing it, since all our choices are the will of the Universe or
waheguru), but simply that we should be aware that we are all a small part of a vast Cosmic Will that is and always will be out of our understanding and ultimate control. As such, we should go about our life duties (
kirt) and raise our families (
gristi jivan), but we should not repent over whatever choices
waheguru has made for us, since everything is His anyway.
Therefore, this means that a "
manmukh" is simply one who refuses to accept his subordinacy to the Universe, and believes that they are in ultimate control. They are, of course, free to believe this. But one should not carry such ego if they are not prepared to face the burden of defeat.
Gurbani warns that those who choose to endure this burden will feel pain when fate appears on their doorstep and they are unable to accept it.
That is my view.
