In my opinion the song is about a person who was loved by another, but yet very confused about his own feelings. Time passed by and the other one grew much older than the man who speaks in the song, which is impossible, as time is the same for everybody. Therefore, this probably means that the one, who loved him is also the one who has become with time more cold and distant. When he says "If I only knew" it shows that he regrets not realizing that they could have had a relationship. The singer had sulfur inside of him, but didn't give it a spark and now he blames himself for his confusion and weakness. Both the wind and the sulfur are metaphors for the love, he had on the inside. Instead of doing anything he "held his head down", which means he was the passive one, while the other person, who loved him, walked around in circles or in other words waited for him, without approaching or forcing him into anything he is not ready for. Whatsoever, that person did knew the one speaking in the song won't do anything, because he is scared. If he knew it too back then, he could have probably done something different. Now he is lost because "there is no light in his pathway" and its all because he didn't give love a spark, there is no flame to lighten his life and show him the way. Therefore he feels regret for it all and desperately asks of the other person for help. However, he has no time for him now.
