japaś ca paramo guhyaḥ
śrūyatāṁ me nṛpātmaja
yaṁ sapta-rātraṁ prapaṭhan
pumān paśyati khecarān

O son of the King, now I shall speak unto you the mantra which is to be chanted with this process of meditation. One who carefully chants this mantra for seven nights can see the perfect human beings flying in the sky.
