It is a fact that no one falls from Vaikuntha. (Bhag. 7.1.35, purp. by Srila A. C. Bhaktivedanta Swami Prabhupada)
The conclusion [of the Jaya-Vijaya "falldown"] is that no one falls from the spiritual world or Vaikuntha planet, for it is the eternal abode. (Bhag. 3.16.26, purp.)
People present many illogical arguments, kutarka. They consider the Lord in Goloka and the eternal transcendental variety, in the form of the eternal relation between the worshipable Lord and His devotees, equal to the temporary activities of the conditioned souls under the influence of maya. Many arguments are raised in such philosophy considering the eternal transcendental objects equal to the material inert objects, but reality is not so. The pastimes of the svarupa-sakti of the Lord are not equal to the temporary endeavors of the conditioned soul in the material world. (Srila Bhaktisiddhanta Sarasvati Thakura, Vivrti on Bhag. 3.7.11)
The jivas have grown out of the jiva-shakti of Sri Krishna. Chit-shaktiis Sri Krishna's full (plenary) shakti, whereas the jiva-shakti is the incomplete shakti. From the plenary potency are produced complete entities, but from the incomplete potency have grown the jivas as atomic chit. Krishna manifests entities of different types in accordance with the kind of the shakti He applies. When established in His essential chit-shakti He reveals His essential Nature as Sri Krishna Himself on the one hand and on the other as Sri Narayana, the Lord of Vaikuntha.
When he desired to have His adherent attendance 'nitya parshada ' servitors in His Transcendental plane Goloka-Vrindavana, Vaikuntha, etc, He through Baladeva created those Eternal Parshada as nitya-mukta jivas at those divine worlds.
He reveals the three Forms of Vishnu, viz., Karanodakasayi, Kshirodakasayi and Garbhodakasayi. At Vraja He reveals His own Nature as Krishna with chit in fullness; as Baladeva, He reveals the eternally free associate jivas for the performance of the eight kinds of service of Himself as Sri Krishna.
Again at Paravyoma (Vaikuntha) He, as Sankarshana, reveals the eternally free associate jivas for the performance of the eight kinds of service to Sri Narayana.
Maha Vishnu, the incarnation of Sankarshana, establishing Himself in the heart of jiva-shakti as Paramatma, creates the jiva-souls of tatastha shakti.
These jivas are susceptible to the influence of maya. Till by dint of God's Grace they get shelter under the hladini (bliss-giving) shakti they are liable to be overcome by maya. Innumerable jivas, overcome fastened by maya, are attached to the three gunas (sattva, rajah, tamah ) of maya.
As such, the conclusion is that it is the jiva-shakti that begets the jivas, and not the chit-shakti." (Bhaktivinode Thakura,Jaiva Dharma, Chapter 15,)
