Or (by the meditation on) the Effulgent Light, which is beyond all sorrow.
In plain words: The mind can also be calmed by meditating on a shining inner light that is beyond all sorrow. The teacher says to picture a lotus in the heart with a bright light inside it.
This is another sort of concentration. Think of the lotus of the heart, with petals downwards, and running through it, the Sushumna; take in the breath, and while throwing the breath out imagine that the lotus is turned with the petals upwards, and inside that lotus is an effulgent light. Meditate on that.
Namaste.
A calm guide to life, the mind and the old teachings.
