“Calling Nityananda as the partial expansions of Ananta, etc. is not His real glories. He is the AVATARI Himself, so everything is possible for Him.” (CC 1.5.126-127)

Nityananda is Balarama, the origin of both the spiritual and material worlds, as revealed in the Vedic scriptures as follows:
● Ananta Samhita of Atharva Veda Shruti
nityanando maha-kayo
bhutva mat-kirtane ratah
vimudhan bhakti-rahitan
mama bhaktan karisyasi
In the Ananta-Samhita, the Lord declares to Anantadeva: “When I appear in Navadvipa in Kali-yuga, You will become Nityananda. You will have a very tall, beautiful, and large body. You will be constantly absorbed in chanting My name and glories. In this way, by Your causeless mercy You will transform many bewildered and lost souls, who are totally devoid of devotion, into My pure unalloyed devotees.”
● Vayu Purana Smriti
balaramo mamaivamsah
so ‘pi mat-prstham esyati
nityananda iti khyato
nyasi-cudamanih ksitau
In the Vayu Purana, the Lord tells Brahma: “Lord Balarama, who is non-different from Me, will also appear by My side as Lord Nityananda. He will become the crest jewel of all renunciants on earth.”
krtvavadhuta-vesam sa
dharman bhagavatan bahun

grhinam asramam tatah
“Assuming the dress of an avadhuta, Nityananda will freely and liberally distribute pure love of God. He will do so first as a brahmacari and later as a householder.”
jahnavy-adibhir atmanam,
darsayisyati manavan.
“Accompanied by His eternal consort Srimati Jahnava devi and many other intimate associates, Nityananda will reveal His transcendental pastimes to the people.”
● Nityananda in the Bhakti Smriti Shastras
● Sri Caitanya Caritamrita
● Nityananda is not just Servitor Godhead but He is also the Avatari Himself, just like Gauranga Krishna

The stem of that lotus is the resting place of the multitude of planets.”
