Science and Spirituality are two opposite side of the universal tree i.e. world. Science emphasis on the physical appearance and outer world as a tree appears above the ground whereas Spirituality explains the root of the universal tree. Both are important but the truth is that science still has been searching the end point.
Without science, spirituality can be elaborate its existence like a root that hold the entire tree in itself before appearing in physical world. Without spirituality or root, science cannot be sustained. When there was no word for science, there was spirituality as science. For example, before searching of the value of Pie (22/7) by the science, there was existence of value pie. Similarly, before the search of gravity, there was also gravity. These law were already in its existence since creation. This eternal knowledge was encrypted by spirituality through various scriptures, great saints, prophets, sage, monk etc.
Technology also a part of evolution where upgraded form of science. Actually, all three parts together work for human welfare. In absence of anyone of them, human life cannot be evolved to higher stage. Before Technology, there was science and before science there was Spirituality.
Without spirituality, we cannot reach to the root source of the life.
