Facebook question: What is Vajra Yogini’s Left Foot Stepping On?

Question Series for my Fb Friends:
Varjra Yogini’s left sacred foot steps on who or what? What is the position of the being She’s stepping on? What is the significance of this being and it’s position? What does this convey to us through Her practice?

Dear Rinpoche, thank you for the very clear explanation. We are very fortunate to have Rinpoche’s blessings 24/7.
With regard to Vajra Yogini’s power of tantra, may I ask for further details why unlike others, Hers gets stronger the further it is from the time of Buddha Sakyamuni? In the video Rinpoche mentioned that it was because she is Heruka and she concquered Mahadewa. May I seek Rinpoche’s indulgence for a further lesson on this?
Thank you
So I know all about the symbols!:-)
