"Shree Vishnu-SahasraNam", Mantra NO. 16:
ॐ क्षेत्रज्ञाय नमः - OM kShetraj~nAya namaH
An excerpt from the extended Tika by Shree Parashara Bhatta (this Tika is entirely devoted to Shree Vaikuntha):
"Bhagavan is called "Kshetrajnah" because He knows the extremely suitable place for conferring on the Released Souls.
The suffix "KA" is added to the root "JNA" (to know) in the word "Kshetrajnah "according to the grammatical rule which says:
"The suffix "KA" is added to a root which ends in "AA" (like jnaa), when it is not preceded by a preposition and the final "AA" of the root is dropped".
The Parama-Vyoma, that is Shree Vaikuntha is referred to here as "Kshetra" (field) because It is the place which yields the crop of Bliss in plenty.
Or "Kshetra" may mean the body of Bhagavan Itself possessed of a similar quality. The Vedic Mantra proclaims:
"Brahman has Akasha (i.e. Vaikuntha) as Its Body".
In Narayaniya (Mahabharata) the goal of attainment by the Mukta, i.e. Paramatma, is specified as the Kshetrajna in the following Sloka:
"Oh Brahma! The goal of attainment for the Muktas is specified as the Kshetrajna".
In the Brahma Purana much is said about Sri Vaikuntha, it begins with these words:
"That is called "Parama-Vyoma" (i.e. Supreme Akasa or Sri Vaikuntha) about which it is said that there is nothing in it (like those that are seen in this world)".
Then it continues:
"The undisputed conclusion is that it is the place known as "Moksha" (Salvation) and that it is the place of Supreme Effulgence; which belongs to Vishnu".
The reputed Brahma Samhita narrates the serial order of the Tattvas and says:
''Parama Purusha resides in the heart-lotus and He is Multi-Faced. He is Omniscient, All-Pervading, and is Himself all things.
He stands enveloping all things. The Pure and Subtle Akasa (Sri Vaikuntha) shines with His Effulgence. That Transcendent world (Paramapada) is like pure crystal and replete with joy.
Those who have realised the Tattvas (rishis) attain this world and are freed from the touch of things both auspicious and inauspicious (i.e. punya and papa).
They are of the size of a trasarenu (i.e. a particle of dust composed of three atoms) and are adorned by millions of rays.
Neither do they take birth in this world nor do they die."
