Serotinous cones, like those in Giant Sequoias, are cones that are covered with a resin. In order for the resin to be melted and the cone to open and release the seeds, it needs to be heated, often by a forest fire. As the fire moves through the forest, the Giant Sequoias get heated and the resin is effectively removed, allowing the seeds to be released and scattered by the wind.
Much like serotinous cones, many of us also go through huge challenges and grave trauma in our life in order to help us grow into stronger, better persons. However, facing big problems, issues, and challenges brings into our lives a level of difficulty and hardship that often seems insurmountable for most of us. This is why it is important to know that there is someone out there ready to guide you through your toughest times and lead you to a better, brighter, more productive tomorrow.
