Where is the naimiShAraNya forest to be found other than in meditation?

Explanation of the felly of the wheel falling off in naimiShAraNya.

In the Srimad Devi BhAgavatam , Chapter II, Book I, "On the questions put forth by शौनक Shaunaka and other Rshis", there comes the reference to the place called NaimiShAraNya, which is a puNya kShetra (holy place).

Literally, NaimiShAraNya translates to 'the forest corresponding to the twinkling of an eye'. Naimish means a measure of time that corresponds to a twinkling of an eye, or the time it takes to close and open an eyelid, and AraNya is forest. Like so many other places mentioned in the PurANas, such as Triveni Sangam (junction of Ganga, Yamuna and Sarasvati which is iDA, pinGala and SushumNA), Sumeru (meru daNDa or the SushumNA nADi), Mount GandhamadanA, KailAsh, etc, this place too is to be found nowhere else but inside the jIva's mind in meditation.

The following is an excerpt from the Chapter in the Srimad Devi BhAgavatam , Chapter II, Book I.

Shaunaka said :-- “O Sûta! What are those Purânas and how many verses are contained in each? Speak all those in detail in this holy Ksettra; we, the residents of Naimisâranya are all very eager to hear this. (Why we call ourselves as the residents of Naimisâranya, hear; you will realise then that no other place exists in this Kali age for hearing the holy discourses on religion) :-- When we were afraid of the Kali age, Brahmâ gave us a Manomaya Chakra (wheel) and I said to all of us :-- Follow this wheel, go after it and the spot where the felly of the wheel will become thin (so as to break) and will not roll further, that country is the holy place; Kali will never be able to enter there; you all better remain there until the Satya age comes back. Thus, acording to the saying of Brahmâ, we have got orders to stay here. On hearing the words of Brahmâ, wo went out quickly keeping the wheel go on, our object being to determine which place is best and holiest. When we came here, the felly of the wheel become thin and shorn before my eyes; hence this Ksettra is called Naimis; it is the most sanctifying place.

The PurANa itself makes this very explicit by describing the Manomaya cakra (wheel made of the mind, or thoughts) that was given by Brahma (the originator of the First thought that Created all Creation). So when the thoughts of the mind are followed in meditation to the Source of the mind, the felly (which is the exterior rim or a segment of the rim of a wheel supported by the spokes) of the wheel falls off as the mind thins. That state in meditation is in the Tapa Loka, where the embodiments of Consciousness, the RShis, see the knower, the act of knowing and the object of knowledge as composed of the three guNas. By meditation and prANAyAma and awakening KuNDalini Shakti and conveying Her to the AjnA cakra, this Tapa Loka is attained. This is the Loka where one can find the NaimiShAraNya and encounter in direct experience the great sages such as SUta, Shuka and great householders such as Shaunaka, and understand their discourses on the PurANas. All this is the fruit of sincere sAdhanA.
