Impersonalists have to understand the unmanifested representation of the Supreme through such Vedic literatures as the Upaniṣads, and they have to learn the language, understand the nonperceptual feelings, and realize all these processes.

BG 12.5, Purport:

So for a devotee there is no difficulty in approaching the Supreme immediately and directly, but for those who are following the impersonal way to spiritual realization the path is difficult. They have to understand the unmanifested representation of the Supreme through such Vedic literatures as the Upaniṣads, and they have to learn the language, understand the nonperceptual feelings, and realize all these processes. This is not very easy for a common man. A person in Kṛṣṇa consciousness, engaged in devotional service, simply by the guidance of the bona fide spiritual master, simply by offering regulative obeisances unto the Deity, simply by hearing the glories of the Lord, and simply by eating the remnants of foodstuffs offered to the Lord, realizes the Supreme Personality of Godhead very easily. There is no doubt that the impersonalists are unnecessarily taking a troublesome path with the risk of not realizing the Absolute Truth at the ultimate end. But the personalist, without any risk, trouble or difficulty, approaches the Supreme Personality directly.
