This song comes from a collection of songs by Shangpa masters.
Khyungpo Naljor, a twelfth-century teacher in Tibet, had a visionary experience in which a lion-headed dakini appeared to him and sang this song about working with dakini energy:

Crystal dakini guards against interruptions.
Jewel dakini increases wealth.
Lotus dakini gathers energy.
Action dakini gets everything done.

When wanting and grasping hold sway
The dakini has you in her power.
Wanting nothing from outside, taking things as they come,
Know the dakini to be your own mind.

The essence of mind is knowing.

Know that the crystal is the non-thought of mind itself,
And the crystal dakini guards against interruptions.

Know that the source of wealth is contentment,
And the jewel dakini fulfills all wants and needs.

Know that the lotus is the non-thought of freedom from attraction,
And the lotus dakini gathers energy.

Know that action has no beginning or end,
And the action dakini gets everything done.

Those who do not understand these points
Can practice for eons and know nothing.

Thus the heart of the matter is
Know the dakini to be your own mind.

Khyungpo Naljor
