If you read our Srimad-Bhagavatam you will find there what is the distinction between realization of Brahman, Paramatma (impersonal Supersoul), and the Personality of Godhead. According to Srimad-Bhagavatam, all of these realizations are on the transcendental plane as much as sunshine, the sunglobe, and the predominating deity on the sunglobe are all full of light and high temperatures. Similarly, either in Brahman, Paramatma or Bhagavan (Personality of Godhead) realization you will always find spiritual light and heat. But as there are different degrees of sunshine, the sunglobe and the sun's deity, similarly there are also degrees of transcendental bliss in the different features of the Absolute. The summary is that the Absolute Truth is the sum total of eternity, bliss and knowledge.
