Translation: 
The sage Maitreya said: Lord Śiva was silent after speaking to Satī, seeing her between decisions. Satī was very much anxious to see her relatives at her father’s house, but at the same time she was afraid of Lord Śiva’s warning. Her mind unsettled, she moved in and out of the room as a swing moves this way and that.
Purport: 

Satī’s mind was divided about whether to go to her father’s house or obey the orders of Lord Śiva. The struggle between the two decisions was so strong that she was pushed from one side of the room to another, and she began to move just like the pendulum of a clock.
