In Jain Dharma, ashubh signs are generally understood as nimitta or indications, but they do not have independent power to control your good or auspicious work.

Main Jain understanding:

• The real cause of success, failure, auspiciousness, or inauspiciousness is karma.
• Good intention, right effort, purity of mind, and right conduct are more important than external signs.
• Ashubh signs may create fear or doubt in the mind, and that can disturb your focus.
• But if your bhavna is pure and your karma supports it, a work can still be successful.

So, in Jain view:

• Do not depend only on signs
• Do not become afraid of ashubh signs
• Focus on samyak darshan, samyak jnan, samyak charitra, and pure effort

In short: ashubh signs may affect the mind, but they do not finally determine auspicious results. Karma and right action matter most.
