Why Sikh only begs from Akal Purakh Waheguru?

ਨਾਨਕ ਬਿਨੁ ਸਤਿਗੁਰ ਸੇਵੇ ਜਮ ਪੁਰਿ ਬਧੇ ਮਾਰੀਅਨਿ ਮੁਹਿ ਕਾਲੈ ਉਠਿ ਜਾਹਿ ॥੧॥
नानक बिनु सतिगुर सेवे जम पुरि बधे मारीअनि मुहि कालै उठि जाहि ॥१॥
naanak bin satgur sayvay jam pur baDhay maaree-an muhi kaalai uth jaahi. ||1||
O Nanak, without serving the True Guru, they are bound and beaten in the City of Death; they arise and depart with blackened faces. ||1||

I wish the English translation would include more non-gender words, like "all of one's hunger is satisfied." instead of "all of his hunger is satisfied." I think everyone understands the true meaning, except a newcomer to Sikhi to whom it may be misleading. There is definitely a need for some more refinement work in Guru Granth Sahib translations. I am thankful for what I have.
