In order to light a lamp a wick is essential. But this alone does not suffice, since oil is also needed. If there is no oil in the lamp the wick will be wholly burnt out. The light will also die out. It is the oil poured into the lamp that protects the wick from burning out. It is only the oil that also helps the lamp burn continuously.

Likewise, if a man does not enjoy the Grace of the Guru his 'prãrabdha' (destiny) will trouble him to the core. This is similar to the wick in a lamp that is bereft of oil. Here it is the Grace of the Guru that is akin to the oil poured into the lamp. 'Prãrabdha' shudders at the prospect of even approaching a 'jivã' who enjoys the Grace of the Guru.

When the lamp contains oil, the wick is protected from burning out even while the lamp is alight. Similarly, 'Prãrabdha' in the life of a 'jivã' does not trouble him who enjoys Guru's Grace.
