In truth, spiritualists are of two kinds: impersonalists who believe only in the spiritual form of God, and devotees of Krishna, who know Him as He really is, that is, in His personal, primordial, original, infinite, and absolute form. For impersonalists, the ultimate goal of existence, the final destination to be attained, is the radiance that emanates from Krishna's fully spiritual body, which forms and composes the entire spiritual world. Because they reject all contact with Lord Krishna, they do not obtain a spiritual body suitable for spiritual action and thus remain mere spiritual sparks, merging into the dazzling radiance emanating from the Supreme Lord.

While devotees of Krishna aim for the spiritual planets floating in the radiance of the spiritual world. By surrendering to Krishna and deciding to serve Him with love and devotion, they obtain a spiritual form that will enable them to continue the active practice of absolute loving service to the Lord.

Indeed, Lord Krishna, the Supreme Personality of Godhead, is the complete form of knowledge, bliss, and eternity, while the formless effulgence is a mere manifestation of knowledge and eternity.

The spiritual planets are also forms of knowledge, bliss, and eternity, and the holy beings, devotees of Krishna, who are admitted to the kingdom of Godhead, each obtain a body of knowledge, bliss, and eternity.

Because of their thirst for pleasure, the impersonalist does not enter the spiritual world.

Impersonalists who aspire to merge into the effulgence emanating from the spiritual body of Krishna, the Supreme Personality of Godhead, but who have no knowledge of the loving and devoted service offered to his personal form in the spiritual world, can be compared to fish that are born in rivers and streams and then migrate to the ocean. It is impossible for them to remain indefinitely in the ocean, for their senses drive them back to the rivers and streams to spawn.

Similarly, the materialist, frustrated in his efforts to find pleasure in our limited material galaxy, will seek impersonal liberation by merging himself either in the causal ocean or in the impersonal effulgence of God.

But because neither offers substitutes for material relationships and sense activity, the impersonalist will have to fall back into the limited material universe and lose himself once again in the cycle of successive deaths and rebirths, driven by the insatiable desire for sense pleasures.

But the saintly being, the devotee of Krishna, who has chosen to engage his senses in devotional service, attains the kingdom of God and there enjoys the company of the Lord and liberated souls, and will never again feel any attraction for the limited attractions of the material world.
