Fabula, El Greco, c. 1600
This wonderful painting is incredibly modern for 1600. The Self-realised painter El Greco depicts a youth blowing on an ember in order to light a candle, overlooked by a monkey and a fool. Perhaps the monkey on the youth's right side represents the quickness and agility, but waywardness, of rajas; while the fool on the youth's left represents the dullness of tamas.
Giving Self-realisation is like one candle lighting another.
The Self realises itself. There is no source of enlightenment beyond the Self. Indeed there is no thing beyond the Self. However, one Self-realised person may ignite Self-realisation in an "other".
In the Sufi tradition, Self-realisation is believed to be transmitted through generations of Sufi masters. This transmission is called Baraka.
