'siddha-loka' - the region of the Siddhas; nāma - named; tāra - of the effulgent atmosphere; prakṛtira pāra - beyond this material nature; cit-svarūpa - full of knowledge; tāṅhā - there; nāhi - there is not; cit-śakti-vikāra - change of the spiritual energy.

That region is called Siddhaloka, and it is beyond the material nature. Its essence is spiritual, but it does not have spiritual varieties.
