परमार्थसार (महामाहेश्वर अभिनवगुप्त - त्रिक-दर्शन, अद्वैत शैव साधना एवं सान्वय सटीक)

24 Paramārthasāra of Abhinavagupta
that the former requires some entity other than it to catch its
reflections, but the latter reflects His own powers in His own
psychic light and appears Himself as His reflections. Ātman is
thus divinely independent and appears in multifarious forms
through His own divine powers of Godhead. It is, besides, not a
chance, but the very essential nature of the Ātman to appear
playfully like that.
राहुरादृश्योऽपि यथा शशिबिम्बस्थः प्रकाशते तद्वत् ।
सर्वगतोऽप्ययमात्मा विषयाश्रयणेन धीमुकुरे ॥ ८ ॥
8. Rāhuradṛśyo'pi yathā
śaśi-bimbasthaḥ prakāśate tadvat
Sarva-gato'pyayamātmā
viṣayāśrayaṇena dhīmukure.
Just as Rāhu does shine and appear in the disk of moon, though
it is otherwise invisible, so does this Ātman shine only in the
mirror of psychic apparatus while witnessing objective reflection,
though it is present everywhere.
Rāhu is the shadow of earth. It moves always in the sky, but
becomes visible only when it becomes focussed on the disk of
moon. Ātman, being infinite in nature, is omnipresent, but
appears as "I" only in the psychic organs of living beings while
having mundane mental experiences. There it forms conceptions
like "I have seen such and such object" and, doing so, appears
as "I". It does not appear like that in any inanimate substances.
आदर्शे मलरहिते यद्वद् वदनं विभाति तद्वदयम् ।
शिवशक्तिपातविमले धीतत्त्वे भाति भारूपः ॥ ९ ॥
9. Ādarśe mala-rahite
yadvad vadanam vibhāti tadvadayam
Śiva-śaktipāta-vimale
dhī-tattve bhāti bhārūpaḥ.
Just as one's face appears clearly in a clean mirror, so does this
Ātman shine as pure consciousness in a mind purified by the
bestowal of the divine grace of Lord Śiva.
God's bestowal of His grace is known as Śaktipāta. It is the
primary factor that directs a being towards the study of divine
scriptures, inspires in him a keen desire to know the truth, gives
rise to devotion for the Lord in his heart, creates contact between
him and a right preceptor and makes him active in the practice
