Translation

Those who worship the demigods will take birth among the demigods; those who worship the ancestors go to the ancestors; those who worship ghosts and spirits will take birth among such beings; and those who worship Me will live with Me. 

Commentary by Srila Prabhupada 

If one has any desire to go to the moon, the sun or any other planet, one can attain the desired destination by following specific Vedic principles recommended for that purpose, such as the process technically known as darsa-paurnamasi. These are vividly described in the fruitive activities portion of the Vedas, which recommends a specific worship of demigods situated on different heavenly planets. Similarly, one can attain the Pita planets by performing a specific yajna. Similarly, one can go to many ghostly planets and become a Yaksha, Raksha or Pishaca. Pishaca worship is called “black arts” or “black magic.” There are many men who practice this black art, and they think that it is spiritualism, but such activities are completely materialistic. Similarly, a pure devotee, who worships the Supreme Personality of Godhead only, achieves the planets of Vaikuntha and Krishnaloka without a doubt. It is very easy to understand through this important verse that if by simply worshiping the demigods one can achieve the heavenly planets, or by worshiping the Pitas achieve the Pita planets, or by practicing the black arts achieve the ghostly planets, why can the pure devotee not achieve the planet of Krishna or Vishnu? Unfortunately many people have no information of these sublime planets where Krishna and Vishnu live, and because they do not know of them they fall down. Even the impersonalists fall down from the brahmajyoti. The Krishna consciousness movement is therefore distributing sublime information to the entire human society to the effect that by simply chanting the Hare Krishna mantra one can become perfect in this life and go back home, back to Godhead.

Commentary by Sri Visvanatha Cakravarti Thakur

"But they are just worshipping those particular devatas according to the rules established in the books describing the method of worshipping those devatas. The vaisnavas worship visnu according what is stated in the books dedicated to Visnu worship. What is wrong if those worshippers follow the instructions of those books?"

That is true, but the rule is this: the devotees of those particular devatas will attain only those particular devatas.

And because the devatas are destructible, how can the worshippers of those devatas become indestructible? But it is understood that the devotees of the Lord are eternal, like the Lord.

aham tv anasvaro nityo mad-bhakta apy anasvarah

I am indestructible, eternal, and my devotees are also indestructible.
