The whole material nature is working under the superintendence of the Supreme Lord. Now, whenever there is any discrepancy, just to rectify, sometimes punishment is given or sometimes the Lord comes Himself, or sometimes He sends His representative, or sometimes He leaves some books of knowledge. In this way, the whole process from God's side is to put ourself always on the right path. That is the process going on.
Now, just like in your Christian religion, Lord Jesus Christ, he claimed himself that he is coming from God as son of God to reclaim you to back to Godhead, back to home. That is the mission. Every . . . every reformer or every great religious leader or God Himself, He comes on this earth to reclaim these conditioned soul to back to Godhead, back to the kingdom of Godhead. That is the whole idea of incarnation.
Now, at the present moment . . . not at the present moment: practically always, the people, by material contact they forget their relation, their relationship with the Supreme Lord, their constitutional position. Now this, whatever we earn, if not the whole thing, but if at least some portion of our income we engage in the service of the Lord for propagating the teaching of God consciousness, that is engaging our fruitive activities, the result of our fruitive activities, in the service of the Lord.
And another thing: if we want to prosecute our spiritual life, then there are certain formulas. Certain formulas mean that we should not take more than what we need. We should not take more than what we need. We should not neglect also that, the portion which we actually need, but at the same time we should not accumulate more than what we need.
