The entire universe has come into existence through one element only. So whatever is created ultimately absorbed into this element. Due to affection and illusion, we see different forms of different things. In such situation it is to be understood that only one element exists in all the living beings. The person who realises this fact remains free from all type of affection, illusion, troublse, misery and temptation. He does not have any troubles or grief. Thus the person who sees oneness in all the visible or invisible elements is the best.
