So where do impersonalists go when their material bodies die?

God, Krishna, helps impersonalists who wish to commit “spiritual suicide” by artificially denying their existence as individual spirit souls, such as Buddhists and atheists.

To this end, He absorbs them into the radiance emanating from His Person. But since they refuse to accept the Absolute Truth, which is none other than Krishna in His personal, real, primordial, original, infinite, absolute, eternal, and blissful form, they cannot, once their individuality is “lost,” experience the bliss of loving service to the Lord. They have no access to the spiritual world, nor can they acquire a spiritual form. They are oriented toward spiritual radiance, and once again become mere fixed spiritual sparks that compose it.

Some, without yet having attained impersonal realization, return to material life to express their latent desire for action. They have no access to the spiritual planets, but are once again offered the opportunity to act on one or another of the material planets that populate the various galaxies.

Impersonalists seek to attain the Impersonal Supreme Spiritual Being, the radiance of the Lord. But ignorant of existential truth, they do not know that this destiny cannot befit the living spiritual spark, an integral part of the Lord. Therefore, they fall from their position and once again acquire various material forms, all alien to the spiritual soul.

All those who uphold the impersonalist doctrine must become a tree in their next life.

Can we act completely independently of God?

In truth, nothing and no one is independent of Krishna, God, the Supreme Personality of Godhead.

The ultimate cause of all creation and all annihilation is none other than the Supreme Lord, Krishna, in His aspect of eternal time.

One day, upon learning that his brother had been killed by the Yaksas, King Dhruva Maharaja decided to seek them out and make them pay for this crime. But as a worthy devotee of Krishna, he felt guilty for having killed so many men.

Having learned of King Dhruva Maharaja's situation and distress, the treasurer of the celestial beings addressed him, telling him that he was free from all sin.

The king, indeed, considering himself responsible for the deaths of many Yaksas, could have considered himself guilty. This is why Kuvera assured him that he had not actually killed any of them, and therefore there was indeed no trace of sin in him.

All things considered, he had done his duty as king, as established by the laws of nature.
