The inhabitants of both Siddhaloka and Vidyādhara-loka are naturally endowed with mystic yogic powers by which they not only can fly in outer space without a vehicle but can also fly from one planet to another simply by exerting their will. Just as fish can swim within water, the residents of Vidyādhara-loka can swim in the ocean of air. As far as the inhabitants of Siddhaloka are concerned, they are endowed with all mystic powers. The yogīs in this planet practice the eightfold yogic mysticism—namely yama, niyama, āsana, prāṇāyāma, pratyāhāra, dhāraṇā, dhyāna and samādhi. By regularly practicing the yogic processes one after another, the yogīs attain various perfections; they can become smaller than the smallest, heavier than the heaviest, etc. They can even manufacture a planet, get whatever they like and control whatever man they want. All the residents of Siddhaloka are naturally endowed with these mystic yogic powers. It is certainly a very wonderful thing if we see a person on this planet flying in the sky without a vehicle, but in Vidyādhara-loka such flying is as commonplace as a bird's flying in the sky. Similarly, in Siddhaloka all the inhabitants are great yogīs, perfect in mystic powers.
The name of Kapila Muni is significant in this verse because He was the expounder of the Sāṅkhya philosophical system, and His father, Kardama Muni, was a great yogī and mystic. Indeed, Kardama Muni prepared a great airplane, which was as large as a small town and had various gardens, palatial buildings, servants and maidservants. With all this paraphernalia, Kapiladeva's mother, Devahūti, and His father, Kardama Muni, traveled all over the universes and visited different planets.
