Every Knowledge is fascinating.
One can exhaust the entire life span in trying to know about a leaf and end up highly unsuccessful ; not even a bit of mission completed.
Every knowledge system is like an uncharted dessert , unfathomable sea and untreaded forest. More you know, more you come to know that the known is but a fraction. But, knowledge is inevitable .Otherwise, normal life would be impossible. Sitting , standing , speaking , eating .... in short , all our life activities are nothing but learned knowledge only. Our feelings of desolate and happiness are but learned behaviour only.
