Draupadi is symbolic of the kundalini energy which awakens the spiritual powers in the spinal centres, chakras, of the devotee, ie, produces a son for each of the Pandava princes in the five spinal centres. So her role is vital. We need her to energise our spiritual efforts and awaken the spiritual properties of the spinal centres. Those spiritual qualities, the 'sons' she gave birth to (and the princes that symbolises them) are:
- Yudhisthira " ether akasha tattva, calmness;
- Bhima " air yayu tattav, prana life force control;
- Arjuna " fire tejas tattva, non-attachment of self-control;
- Nakula " water ap tattva, power to adhere to good rules; and
- Sahadeva " earth kshiti tattva, power to resist evil.
Karna is symbolic of the propensity for pursuing material action, toward which there is natural attachment because of the pleasure derived from it. Karna is Patanjali's raga. "Raga is that inclination (attachment) which dwells on pleasure." He is the half brother to the Pandavas, son of Surya, the sun, the light of the kutastha spiritual eye, and Kunti (the power of invoking spiritual energy), before she married Pandu (divine discriminative power). Karna became a friend of Duryodhana (symbol of vainglorious desire) and out of spite became an enemy of the Pandavas, especially Arjuna.
You can see how the symbolism ties in:
Because Kunti, the power of invoking spiritual energy, is not yet united with the divine discriminative power, or Pandu, the offspring Karna (attachment to pleasure) comes under the influence of the material sense inclinations (Duryodhana and 99 brothers) and so sides with them in the inner battle (Kurukshetra) in opposition to the righteous (Pandava) spiritual qualities. The word 'karna' also means 'the helm of a ship', so symbolically the consciousness represented by Karna, born of the light of the spiritual eye but reared by Dhritarashtra, may be 'steered' either inwardly through the door of of the spiritual eye or outward into the senses and material consciousness. Karna feels a duty to be loyal to Duryodhana, material desire. So raga, or Karna, is the main actor in the deluded man that causes him to seek actions he is attached to because of the pleasure he gets. He rationalises and justifies (just like we do!) by saying it is his duty.
So was Draupadi in love with Karna? And how does that teach us anything?
Draupadi, the kundalini energy, is essentially neutral but wants us to make the right choices. We can do that if we use our inner soul qualities. As Karna is the downfall of our spiritual pursuits and the enemy of those inner soul qualities, it would seem logical that no, she was not in love with him.
