sat-cit-ānanda-maya—full of eternity, knowledge and bliss; haya—is; īśvara—of the Supreme Lord; svarūpa—the transcendental form; tina aṁśe—in three parts; cit-śakti—the spiritual potency; haya—becomes; tina—three; rūpa—forms.
"The Supreme Personality of Godhead in His original form is full of eternity, knowledge and bliss. The spiritual potency in these three portions [sat, cit and ānanda] assumes three different forms.
According to the verdict of all Vedic literature, the Supreme Personality of Godhead, the living entity and the illusory energy (this material world) constitute the subject matter of knowledge. Everyone should try to understand the relationships among them. First of all, one should try to understand the nature of the Supreme Personality of Godhead. From the śāstras we understand that the nature of the Supreme Personality of Godhead is the sum total of eternity, bliss and knowledge. As stated in verse 154 (viṣṇu-śaktiḥ parā proktā), the Supreme Personality of Godhead is the reservoir of all potencies, and His potencies are all spiritual.
