This is the OG way of carrying things before backpacks became cool. Think of a farmer with a sack of rice on his shoulder, or Jesus carrying the cross—that's **pasang**. In modern life, it's the invisible weight of your responsibilities, your "kruses sa buhay." When you say, "Ang bigat ng **pasang** ko ngayon," you're not talking about a sack of rice, you're talking about deadlines, bills, and adulting in general.
