Long for a hundred years long life.

Long for a  hundred years long life by doing specified actions as duties of this world. Thus the actions and their fruits shall not get attached to the humans. There is no way other than this (To get salvation from the bond of actions). Ishavashya Upanishad 1/2.

Since The God is the owner of this world. Hence the humans are to remember The God and use and enjoy the world by understanding that and by worshipping The God by own actions wish to live for hundred years long life. Thus the whole life must be submitted to The God. And every action should be done in favor of The God, to please Him and to worship Him and to serve Him. World is available for the worship and actions are available for enjoyment and not for own self. By doing thus the humans shall not be bounded by the actions and their fruits. Hence this is the only way to liberation from the bandage. There is no other way for salvation.
