Śrī Caitanya Mahāprabhu said, “Today I have conquered the three worlds very easily. Today I have ascended to the spiritual world.”
Purport: 

The goal of human perfection is stated here in brief. One has to surpass all the planetary systems of the material universe, pierce through the covering of the universe and reach the spiritual world, known as Vaikuṇṭhaloka. The Vaikuṇṭhalokas are variegated spiritual planets situated in the Lord’s impersonal bodily effulgence, known as the brahmajyoti. One may aspire to elevate himself to a heavenly planet within the material world, such as the moon, the sun or Venus, but if one is spiritually advanced in Kṛṣṇa consciousness, he does not wish to remain within the material universe, even in a higher planetary system. Rather, he prefers to penetrate the covering of the universe and attain the spiritual world. He can then be situated in one of the Vaikuṇṭha planets there. However, the devotees under the guidance of Śrī Caitanya Mahāprabhu aspire to reach the topmost spiritual planet, known as Goloka Vṛndāvana, the residence of Lord Śrī Kṛṣṇa and His eternal associates.
