Hare Krsna
 
Below are two very good points that Prabhupada makes
 
1.) For the materialists, all their work ends up as ZERO–at death, nobody takes a cent with them. So for a devotee, if we work 75% of the time for Krsna, that means 25% of our time it is for Maya. The 75% goes with us next lifetime, the 25% stays here in the material world. This is a waste of energy.
 
2.) For the devotees, this argument about taking to spiritual life is a no brainer. Who but a madman would work for nothing? But that is what all karmis or materialistic people are doing.
But for the devotees, Srila Prabhupada is encouraging us all to make this the final lifetime and work now towards that end. Why? Because if you have to work, which we all do, then why not work for Krsna and be finished once and for all with these material problematic bodies and repeated birth/death.?

. It is being automatically done. Two plustwo equal to four. Similarly, whatever we are doing, we are preparingfor the next life. Karmaṇa. Simply material nature has to give you a post: “Now you have done like this. Take this post.” You cannot deny. You cannot say, “No, no, I don’t like this post.” No, you have to take it. So for the karmīs, even they have done their so-called duties very perfectly well, what is the profit? There is no profit, because we are under the control of material nature. But the devotees, whatever little service they have done, that is permanent asset. That is not controlled by nature. That is controlled by God.

 
…….But they do not believe in the next life, although it is very common sense. Actually there is next life because Kṛṣṇa says, and we can understand the philosophy by a little intelligence that there is next lifeSo our proposition is that “If you have got to prepare yourself for the next life, then why don’t you take the trouble of preparing for going back to home, back to Godhead?” This is our proposition. You can prepare yourself to go to hell or heaven. That doesn’t matter because that is also temporary. Kṣīṇe puṇye punar martyalokaṁ viṣanti. After you have finished… Just like you may go to jail or to somewhere else. When your visa or time is finished, then you are free from such life. Similarly, even if we go to the heavenly planet, when the resultant action of our pious activities are finished, then again we are turned down here. So in this way sometimes higher planetary, sometimes lower planetary, we are traveling. Therefore our best business is: “Why not go back to home, back to Godhead?” Kṛṣṇa says, madyājino ‘piyānti mam: [Bg. 9.25] “Anyone who is Kṛṣṇa conscious, he comes to Me.” So why not go to Kṛṣṇa? Then the question will be: “What is the benefit of going to Kṛṣṇaloka? What is the difference between going to heavenly planet or any other planet and going to Kṛṣṇa?” The difference is, any planet go, you are under the four material regulation,janmamṛtyujarāvyādhi: [Bg. 13.9] birth, death, old age and disease. But if you go to Kṛṣṇa… Yad gatvā na nivartante tad dhāma paramaṁmama [Bg. 15.6]. If you go to Kṛṣṇa, then you don’t get any more chance to come down and take a material body. You can live there eternally blissful life of knowledge. That is the difference.

So any intelligent man should take to Kṛṣṇa consciousness, cultivate the Kṛṣṇa conscious business and go back to home, back to Godhead, for eternal life. This mission we are preaching all over the world because Śrī Caitanya Mahāprabhu wanted it. Śrī Caitanya Mahāprabhu wanted to deliver the fallen souls from the clutches of māyā and take them back to home, back to Godhead.   Atlanta March 1 1975

So to forget Krsna and to become subjected to the condition of
material nature, that is called material life. Material life means to
give up the idea of going back to home, back to Godhead, but making
plan here to be happy. This is called maya, or material life.
