In Jain Dharma, the main principle is ahimsa — causing minimum harm to living beings.

So, a vegan burger or meat substitute is not automatically wrong. It depends on what it contains and how it is made:

• If it is fully plant-based and does not contain animal products, then it is generally more aligned with Jain ahimsa than meat.
• If it contains roots like onion, garlic, potato, etc., then it is not suitable for strict Jain practice.
• If it contains eggs, dairy from doubtful sources, gelatin, or any animal-derived ingredient, then it is not acceptable in Jain diet.
• Even if plant-based, if it is highly processed, wasteful, or encourages attachment to taste and imitation, some may avoid it as a matter of simplicity and restraint.

So the simple Jain view is:

Plant-based meat alternatives are not wrong by themselves, but only if they remain within Jain dietary rules and support ahimsa.

For a strict Jain, the safest rule is: choose simple, pure, plant-based food that avoids injury and avoids forbidden ingredients.
