The ability of the pawns is limited, but if a pawn will show courage, consistency and passion in the service of his love, she can become a Queen. A Queen is someone who loves the king passionately. The king is mind, truth and perfection.
Life is like chess, but there are many differences. Life is multidimensional, there are many players, the rules change dynamically, many pieces, including pawns independently decide where to go and the king only indirectly affects the moves of his pieces. Moreover, in real life, unlike chess, their pieces can "eat" their own.
