Patience is very important in life because there are so many things that take time to develop for us to experience in a positive way. Of course we want everything right here right now, but that is not always the way it works. It takes time to build anything of any significance in life. A building, for example, cannot be sustainable and inhabitable without a lot of hard work put into constructing the foundation. If we were not patient with the building of the house and dedicated to it and believed that we could create it, it would have never been developed.
The good things in life take time. Sometimes we come into life for the mere experience of pain and suffering. Where we come from originally, we are always in love and experience great bliss, so sometimes when we come here we spent a great portion of our lives suffering and we wonder why. The reason is because pleasure isn't as enjoyable without the pain, so we have to be patient and endure our lives and accept our situations to be able to experience the bliss that we so rightfully deserve.
Patience is important in life because if we try to make something happen, we put a lot of stress on ourselves. Life is not about living in the future or in the past. Life is about accepting the present moment. Patience is probably the biggest lesson for man to learn because with infinite patience, we are infinitely merciful and accepting and forgiving. With unlimited patience we can accept any circumstance and are truly free. We are in need of nothing and are happy just to be as we are. The key to enlightenment is patience. Practice and mediate on the concept and you will find that you have found the keys to eternity.
Once we develop our patience and are in need or want of nothing, we find ourselves with everything and lack nothing. This comes though, not overnight. Patience usually comes through a lifetime of refinement and suffering, or through spiritual discipline and education. However you find it though, make sure that you do, because when you do, you will be rewarded beyond measure.
