In Śvetāmbara Jain tradition, adhivāsanā and añjana-śalākā are different parts of the temple idol consecration process.

1. Adhivāsanā

• Meaning: A preparatory sanctification ritual.
• Purpose: To spiritually prepare and invoke auspiciousness before the main consecration.
• It is done to purify the idol, the place, and the surrounding atmosphere.
• It is generally a preliminary ceremony before the main pratiṣṭhā process.

2. Añjana-śalākā

• Meaning: The ritual in which a special instrument called añjana-śalākā is used on the eyes of the idol.
• Purpose: It is considered the main consecration act that symbolically infuses life-presence / sacred visibility into the idol for worship.
• In many Śvetāmbara traditions, this is treated as a very important central step in temple installation.

Main difference

• Adhivāsanā = preparatory sanctification
• Añjana-śalākā = main consecration act using the ritual stylus

Simple way to remember

• Adhivāsanā comes before and prepares.
• Añjana-śalākā is the special consecration step that follows in the installation process.

In short, adhivāsanā is the preparation, while añjana-śalākā is the sacred installation ritual itself in Śvetāmbara practice.
