Inside the main circle, in the centre is the “stupa” (pillar) with concentric rings holding a lotus flower on its top on which is the illuminating flame.
The pillar represents Yoga, with a number of rings to indicate the stages of Yogic Sadhana. This Yoga leads to the unfolding of the Lotus of the Heart, whose petals are borne on top of the pillar. The next stage of this consummation of Bhakthi and the blossoming of the Heart is the Flame of Jnana, the Illumination, the Jyothi, which is symbolised as the finale of the Sthambha (pillar). The Yoga fructifies and takes the sadhaka (spiritual aspirant) on from one height to another, until the Lotus of the Heart blooms and the Effulgence of Illumination is vouchsafed at last.
