Answer

In Paryushan, some Jains avoid using a blender because it is a fast electric machine that may cause more violence to tiny living beings and may encourage more processing, grinding, and careless food preparation.

A mortar and pestle is usually considered more acceptable because it is manual, slower, and used in smaller quantity with more awareness.

Explanation

During Paryushan, the aim is to reduce himsa and increase jagruti — spiritual awareness.

A blender:

• rotates at very high speed,
• crushes ingredients very finely and forcefully,
• may kill more tiny organisms present in food, water, or air,
• can create heat and disturbance,
• makes food preparation quicker and less mindful.

A mortar and pestle:

• works by hand,
• is slower and more controlled,
• usually processes a smaller quantity,
• encourages mindfulness and restraint.

So the distinction is not merely “machine versus hand tool.” The deeper Jain concern is minimizing unnecessary violence, reducing indulgence, and preparing food with care.

Spiritual Understanding

Paryushan is a time of samyam — self-restraint. Many rules followed during this period are stricter than everyday practice because the focus is on purification of the soul.

Avoiding blenders can be understood as a practical discipline to:

• reduce avoidable harm,
• simplify food habits,
• avoid excessive taste and convenience,
• practice greater awareness in daily actions.

Takeaway

A mortar and pestle is generally seen as more mindful and less forceful, while a blender is avoided because it is high-speed, electric, and may involve greater subtle violence. The purpose is not just the rule itself, but the Jain spirit of ahimsa, restraint, and awareness during Paryushan.
