SB 5.24.5
tato ’dhastad yaksa-raksah-pisaca-preta-bhuta-gananam viharajiram antariksam yavad vayuh pravati yavan
megha upalabhyante.
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Beneath Vidyadhara-loka, Caranaloka and Siddhaloka, in the sky called antariksa, are the places of enjoyment for the Yaksas, Raksasas, Pisacas, ghosts and so on. Antariksa extends as far as the wind blows and the clouds float in the sky. Above this there is no more air.
