The Great Liberation Tantra

Becomes pleased, as he is the Soul of the Universe, and the universe depends on Him. (33)

He is the One, the essence of existence, the Truth, the Non-dual, the Supreme of the Supreme.
Self-luminous, always full, and characterized by Being, Consciousness, and Bliss. (34)

Immutable, without support, without attributes, without confusion.
Beyond the qualities, the witness of all, the Soul of all, the All-seeing, the All-pervading. (35)

...the controller of all, the Supreme Lord becomes pleased. If one asks how pleasure arises in the Supreme Lord due to the creation of world-welfare, he says "Vishvatma." Because even though the Supreme Lord is the Soul of the Universe, pleasure arises in Him through the creation of world-welfare; that is the meaning. If one asks how He can be the Soul of the Universe, he says "Yato vishvam" etc. Because the universe is dependent upon Him, the Supreme Lord, He is the Soul of the Universe. (33) He establishes that the Supreme Self alone is of one nature and truth, while all other objects are illusory. Regarding "Sa eka eva" etc.: Since He is Truth, and since knowledge of Him brings pleasure to all and is the cause of all objectives, the Supreme Self alone is to be meditated upon, worshipped, and easily propitiated. First, he states that the Supreme Lord is the only Truth, of the nature of Existence. All other objects are to be known as untrue. He shows the cause of His truth by saying "Advaita" etc. Because He is non-dual, free from internal and external distinctions, He is superior to Brahma and others; therefore, He is supreme. He shines by His own Self; hence, He is self-luminous, meaning He does not depend on the light of the sun, moon, etc. He is "Sada-purna," always complete, and characterized by Being, Consciousness, and Bliss; that is, He is the nature of Existence, Consciousness, and Bliss, which are always enduring. (34) "Nirvikara" means free from change, which is the alteration of nature. "Niradhara" means without a support. "Nirvishesha" means devoid of internal distinctions. "Nirakula" means free from agitation. "Gunatita" means having transcended the qualities (such as heat, cold, happiness, sorrow, or the three gunas). "Sarvasakshi" means the direct witness of all auspicious and inauspicious deeds. "Sarvatma" means of the nature of all. "Sarvadrik" means the seer of all objects. "Vibhu" means one who has attained all things. (35)
