(Based on the commentary of Parasara Bhattar)
If music gives expression to emotion, singing the glory of the Lord saves a person from the power and penalty of sin and confers eternal happiness. Illustrations to demonstrate this easy way to attain the bliss are abundant as one takes a journey into the world of Hinduism. It is in this context that Kaisika Mahaathmiyam gains the relevance. It is simple story but the significance of the narration lay in the message it conveys ultimately for righteous living.
Among the Avatars most unique of the Lord (Emperuman) is His appearance twice as Varaha, the form of a wild boar. Once, Mother Earth (who is none elsebut the Goddess Bhoomi Piratti) sank into the sea to save herself from the tyranny of an Asura called Hiranyaksha. Responding to her cry, Lord Mahavishnu, came as a boar, fatally knocked down the Asura, retreived her from the position and consoled her by revealingthe message of the vedas. The Earth was again populated and the Ten incarntions of the Lord refer to this appearance of Varaha.
The second time when He showed up was the save the earth from a great devastation called Paralayam (deluge). Lifting the earth, drowned by sea, on His tusker teeth, Varaha placed the planet back in its proper orbit. Even as He wiped the sorrow of Bhoomi Piratti and was comforting her, the Mother Earth expressed sadness at the sufferings of the people and sought the benign blessings of Emperuman on them and beseeched Him to show an easy way to attain salvation for those submerged in the ocean of family bonds and affinity.
Readily acceding to the request of the Piratti whose upper most concern was the welfare of her children on earth, Emperuman suggested tht by performing musical offering and singing His glory in great faith, the devotees could please him Him gain moksha, the ultimate universal bliss.
As perfectly said, Music is the one which connects us with the Almighty. Singing the glory of the Lord will take us to the heaven and gives us delightful life. In our short span of our life which itself is all directed by the Almighty, let us think only about him. This is another way of meditation. By doing this we are sure to avoid so many unnecessary and unwanted things getting inserted into our mind and thus we stay pure which the Almighty likes in us.
