In Hellboy, it is to say that all human beings have a hole in their hearts, for nothing can ever be used to fill it up, be it power, money, love and the list goes on; probably. Obviously all that are named can be used as fillers, but the problem is, can they hold long enough to last for eternity? Passion lives inside us, which would burn all sorts of desires and needs, questions and answers, love and emotions, expression and disguise; hence, forming a bottomless pit. Reasons why we loose certain passion as the time goes by, reasons why there are those which never last for long and reasons why it remains bottomless as it is even after life; if we never figure out how and why. The reason why we never stop; never once we stop loving, never once we stop feeling pain, never once we stop being emotional, never once we stop behaving not us. Solution to make the filler stays? Never once should we stop filling it up. We have the same black hole in us, but we’re using different fillers as we continue the journey of life. It could be similar, but will never be the same, as we may be using different quality and quantity, or even mixtures; creating our very own fillers. Same goes to our life time experiences, where we may have been through the similar situations, but somehow differ from one to another. What sort of filler you've chose?
