YogaMurti, 

It is rare for a yogi to gain access to an astral location like this. Usually, one does not get beyond the guardians. That is due to bad practices and especially to being indulgent in sensual habits which run contrary to advancement in yoga.

This place is not in siddhaloka but it is comparable to that place because it was originally established by the deity Avalokeshwara for ascetics who needed to advance further but who could not reach siddhaloka. One cannot reach this place if one has disciples or if one has social friends who accompany one when one tries to transfer to this place. This is a place for single serious ascetics.
