moksha

"Moksha" is the highest PURUSHARTHA=accomplishment of our body after fulfilling the other purushartha in the life per scriptures.
Nandji, you are partly right about Paramartha. By doing help and thinking about others, we are offered Grace= Kripa from the Lord.
Without Kripa, we will never be able to consumate or have the fruits of all our Karma from Time immemorial. In fact we do not have the fruits of all these Karma, He is so much merciful that He pardons all Karma and then only we have this State of Mind , Moksha and when we leave this body, He will take us to His abode for eternal service. We will not merge never into the Lord, yet we will enjoy more than Atma-Sakshahtakar
