Purport: 

People are very anxious to understand the Absolute Truth in various ways, especially by experiencing the brahmajyoti, or Brahman effulgence, by meditation and by mental speculation. But Kapiladeva uses the word mām to emphasize that the Personality of Godhead is the ultimate feature of the Absolute Truth. In Bhagavad-gītā the Personality of Godhead always says mām, “unto Me,” but the rascals misinterpret the clear meaning. Mām is the Supreme Personality of Godhead. If one can see the Supreme Personality of Godhead as He appears in different incarnations and understand that He has not assumed a material body but is present in His own eternal, spiritual form, then one can understand the nature of the Personality of Godhead. Since the less intelligent cannot understand this point, it is stressed everywhere again and again. Simply by seeing the form of the Lord as He presents Himself by His own internal potency as Kṛṣṇa or Rāma or Kapila, one can directly see the brahmajyoti, because the brahmajyoti is no more than the effulgence of His bodily luster. Since the sunshine is the luster of the sun planet, by seeing the sun one automatically sees the sunshine; similarly, by seeing the Supreme Personality of Godhead one simultaneously sees and experiences the Paramātmā feature as well as the impersonal Brahman feature of the Supreme.

The Bhāgavatam has already enunciated that the Absolute Truth is present in three features — in the beginning as the impersonal Brahman, in the next stage as the Paramātmā in everyone’s heart, and, at last, as the ultimate realization of the Absolute Truth, Bhagavān, the Supreme Personality of Godhead. One who sees the Supreme Person can automatically realize the other features, namely the Paramātmā and Brahman features of the Lord. The words used here are viśoko ’bhayam ṛcchasi. Simply by seeing the Personality of Godhead one realizes everything, and the result is that one becomes situated on the platform where there is no lamentation and no fear. This can be attained simply by devotional service to the Personality of Godhead.
