Translation: 
When Kṛṣṇa opened His mouth wide by the order of mother Yaśodā, she saw within His mouth all moving and nonmoving entities, outer space, and all directions, along with mountains, islands, oceans, the surface of the earth, the blowing wind, fire, the moon and the stars. She saw the planetary systems, water, light, air, sky, and creation by transformation of ahaṅkāra. She also saw the senses, the mind, sense perception, and the three qualities, goodness, passion and ignorance. She saw the time allotted for the living entities, she saw natural instinct and the reactions of karma, and she saw desires and different varieties of bodies, moving and nonmoving. Seeing all these aspects of the cosmic manifestation, along with herself and Vṛndāvana-dhāma, she became doubtful and fearful of her son’s nature.
Purport: 

All the cosmic manifestations that exist on the gross and subtle elements, as well as the means of their agitation, the three guṇas, the living entity, creation, maintenance, annihilation and everything going on in the external energy of the Lord — all this comes from the Supreme Personality of Godhead, Govinda. Everything is within the control of the Supreme Personality of Godhead. This is also confirmed in Bhagavad-gītā (9.10). Mayādhyakṣeṇa prakṛtiḥ sūyate sa-carācaram: everything in the material nature (prakṛti) works under His control. Because all these manifestations come from Govinda, they could all be visible within the mouth of Govinda. Quite astonished, mother Yaśodā was afraid because of intense maternal affection. She could not believe that within the mouth of her son such things could appear. Yet she saw them, and therefore she was struck with fear and wonder.
