In Jainism, pooja (puja) is usually a simple, inner-oriented act of reverence to the Tirthankaras and to the principles of right conduct. The common, accepted offerings are things like water, fruit, flowers, light (lamp), and incense—focused on purity, non-violence, and sincerity.

Kesar (saffron) is not a standard or essential element of Jain puja. It is more commonly associated with other traditions where fragrance, color, or auspicious symbolism play a larger role. If kesar is used in some households, it would be as a fragrant, decorative adjunct or as part of a broader festival tradition, not as a required or universal component. There’s no rigid prescription in Digambara or Śvetāmbara practices that mandates saffron in worship.

Bottom line: saffron is optional and not a defining part of Jain worship. The emphasis remains on simple, pure offerings and a mood of humility and non-attachment.
