"Lagna mandap ma aapyu mujne pancham gyan" is a phrase often heard in Jain wedding songs and rituals. In this context, it is poetic language rather than a literal doctrinal statement.

In Jain philosophy, "Pancham Gyan" refers to "Keval Gyan" (omniscience), which is the fifth and highest form of knowledge attained by an enlightened soul (Kevali). The five types of knowledge (Gyan) in Jainism are:

1. Mati Gyan (Sensory knowledge)
2. Shrut Gyan (Scriptural knowledge)
3. Avadhi Gyan (Clairvoyance)
4. Manahparyav Gyan (Telepathy)
5. Keval Gyan (Omniscience)

In the wedding context, the phrase "aapyu mujne pancham gyan" expresses that, on the auspicious occasion of marriage in the "lagna mandap" (wedding altar), the person feels as if they have attained the highest knowledge or bliss. It is an expression of supreme happiness and fulfillment, comparing the joy of marriage to the ultimate spiritual achievement in Jainism.

Note: This is a metaphorical usage and should not be confused with literal attainment of Keval Gyan, which, according to Jainism, is possible only after intense spiritual practice and the destruction of all karmas.
