[Advaita-l] 'lens-grass' burning analogy

[H S Chandramouli]

Namaste Sri Subrahmanian Ji,

Reg  << 'lens-grass' burning analogy

I am looking for the reference of an analogy used in the texts to show that
'svarupa jnanam does not directly annihilate avidya, but when directed
through a vritti, it does the job'. The analogy is: sun directly does not
burn a blade of grass but when directed through a glass/lens, it burns.
This analogy is in some prakarana grantha or vyakhyana.  Any help in
locating the text is appreciated. >>,

The illustration is in the context of explaining that the self same
Consciousness can be the locus as also the annihilator of  aj~nAna under
different circumstances. The nearest reference I could get immediately is
from Advaita Siddhi,  pp 577.

<< वृत्यवच्छेदेन तस्या एवाज्ञानविरोधित्वात्, स्वतस्तृणतूलादिभासकस्य
सौरालोकस्य  सूर्यकान्तावच्छेदेन स्वभास्यतृणतूलादिदाहकत्ववत्
स्वतोऽविध्यातत्कार्यभासकस्य  चैतन्यस्य  वृत्त्यवच्छेदेन  तद्दाहकत्वात्। >>

<< vRRityavacChedena tasyA evAj~nAnavirodhitvAt,
svatastRRiNatUlAdibhAsakasyasaurAlokasya sUryakAntAvacChedena
svabhAsyatRRiNatUlAdidAhakatvAt svato.avidhyAtatkAryabhAsakasya caitanyasya

<<  Although Pure Consciousness is devoid of the destructive potentiality
of aj~nAna  It receives the power of annihilating aj~nAna when It becomes
reflected in the mental mode. The rays of the sun illumine a piece of
cloth. But the same piece of cloth is burnt up when the same solar rays
become  focussed upon it by means of a piece of convex lens. >>
