This is an active meditation for calling on the power of Durga.
Wherever you are, imagine the form of Durga coalescing out of your surroundings – out of the sky, earth, furnishings, drawing crackling strands of electricity out of nearby power sockets, a corona of energy about her. Visualise the form of Durga forming above you. Feel her feet upon your head, sending shockwaves of power through your body, and imagine yourself to be seated on the back of her tiger. Feel the power of Durga coursing through you and meditate upon her qualities.
The weapons which Durga bears (given to her by the gods) can be taken, in this meditation, as ‘attachments’ – things which you think you need; tools which you perhaps rely too much on. As Durga defeated Mahisa by herself, so too, your power and poise resides in you, rather than your tools and attachments.
