You can conduct a puja, any puja, with an elaborate set of sāmagri (items), or just one flower. What matters is the feeling within. Likewise, Deepawali can be celebrated with an array of dazzling lights, or just one diya, that lights the Jnana Jyothi (the inner wisdom)…the many diyas in your mind are lit by this one Jyothi, thus creating the wali (array) of deepas…resulting in Deepawali.
What do you need to light a diya? Four main ingredients – an earthen diya, oil, a cotton wick and a match. Likewise, you need four ingredients to light your inner diya – Vairagya (detachment) as the earthen diya, Bhakti (devotion) as the oil, Ekāgrata (single-mindedness) as the cotton wick, and Jnana (knowledge) to provide the spark.
One of the stories associated with Deepawali is the slaying of Narakāsura, by Krishna and Satyabhama. It is said that Krishna then “married” the 16,000 wives of Narakāsura. Seems pretty fantastic a story, yes?
Narakāsura ruled at Pragjyotishapuram. The word Pragjyotishapuram comprises Prag (before), jyoti (light), sha (forgot) and Puram. The city where the light of Jnana was absent, hence Pragjyotishapuram. One who travels towards ignorance is Naraka…and so Krishna got rid of Narakāsura, and brought the light of Jnana to the people of the city.
But why marry 16,000 women?
Well, they weren’t women in the first place.
In the human body, there are what are called “Chakras”, or seven spiritual nādis or centers. Of these, the two most important are: the Anāhata (the Heart) and Sahasrāra (the thousand-petal chakra). The Anāhata is also known as the Lotus of the Heart, and has eight petals. These eight petals symbolise the eight worlds, the eight directions, the eight guardians of the world…Because Krishna was the Lord of these eight petals, he was described as the husband of these eight queens. The ‘master’ is called ‘Pati’ and those under him are described as wives. This is a symbolic relationship in the worldly sense.
Similarly, the Sahasrāra is called the thousand-petalled Lotus (if you haven’t seen it already at the yoga studio next door). Each petal has sixteen phases or kalas, representing the sixteen phases of the moon. And so Krishna, being the Lord of the sahasrāra, is the pati of the sixteen thousand kalas contained in it – hence misinterpreted as one who has 16,000 wives.
