BG 2.2, Purport:

"The Absolute Truth is realized in three phases of understanding by the knower of the Absolute Truth, and all of them are identical. Such phases of the Absolute Truth are expressed as Brahman, Paramātmā, and Bhagavān."

These three divine aspects can be explained by the example of the sun, which also has three different aspects, namely the sunshine, the sun's surface and the sun planet itself. One who studies the sunshine only is the preliminary student. One who understands the sun's surface is further advanced. And one who can enter into the sun planet is the highest. Ordinary students who are satisfied by simply understanding the sunshine—its universal pervasiveness and the glaring effulgence of its impersonal nature—may be compared to those who can realize only the Brahman feature of the Absolute Truth. The student who has advanced still further can know the sun disc, which is compared to knowledge of the Paramātmā feature of the Absolute Truth. And the student who can enter into the heart of the sun planet is compared to those who realize the personal features of the Supreme Absolute Truth.
