Gnosis. A

 Here’s a concise comparison between the mysticism of the Gospel of Philip and Advaita Vedanta (associated with Adi Shankaracharya):

Theme	Gospel of Philip (Gnostic mysticism)	Advaita Vedanta (Nondualism)
Ultimate Reality	Hidden divine fullness (Pleroma); transcendent source beyond the material world	Brahman is the only reality; infinite, nondual consciousness
Problem	Ignorance (veil) hides divine origin; world seen as fragmented	Avidya (ignorance) makes one think self is separate from Brahman
Salvation	Gnosis (revealed knowledge) tears the veil and restores unity	Self-knowledge (Atman = Brahman) removes ignorance
Self	Divine spark trapped in material existence	True self (Atman) already identical with Brahman
World	Often viewed as illusory or lower-order emanation	World is Maya — appearance, not absolutely real
Christ / Guru role	Christ reveals hidden knowledge and symbolic sacraments	Guru points to nondual truth; no savior needed
Union	“Bridal chamber” symbolizes reunion of divided being	No real separation; realization of ever-present unity
Veil concept	Veil separates sacred knowledge from ordinary perception	Ignorance veils the identity of Atman and Brahman
Path	Mystical insight, symbolic sacraments, inner awakening	Inquiry (Jnana), discrimination, meditation
End state	Restored fullness, spiritual wholeness	Moksha: realization of nondual awareness

In one line:

• Gospel of Philip: “You are divine but forgot — Christ reveals it.”
• Advaita: “You are Brahman already — ignorance hides it.”

Want me to also compare:

• Buddhism vs these two
•  Sufism vs these two
