The translation by Prabhavanda & Isherwood is my favourite. There was one verse/shloka about karma yoga that was my motto for nine long years.
"Whole of humanity was born for perfection and everyone will reach it if he answers the call of duty that belongs to his nature."
(In Dutch, damn hard to translate)
"Heel de mensheid is geboren voor volmaaktheid en eenieder zal die ook bereiken als hij gehoor geeft aan de plicht van zijn aard."
I regret that I now have difficulty believing in anything but that is, I am afraid, the natural result of a betrayal.
