There can be many reasons, and it is not true for all Jains in the USA. Many Jains do practice sincerely, but some feel less connected after moving abroad.

Common reasons include:

• Busy lifestyle: Work, study, and family routines leave less time for prayer, samayik, swadhyay, and temple visits.
• Less religious environment: In India, Jain culture is often present in daily life. In the USA, one must make more effort to stay connected.
• Language and scripture gap: Some people do not understand Prakrit, Sanskrit, Gujarati, or Hindi well enough to follow teachings deeply.
• Distance from temples and sangh: Many cities have few Jain temples or no regular spiritual programs.
• Children growing up in a different culture: Younger generations may know Jain identity but not the full practice.
• Focus on social identity more than discipline: Some families keep Jain identity by name, food habits, or festivals, but do not follow deeper vows and practices.
• Weak guidance: Without regular sadhu-sadhuvishay, classes, or elders teaching dharma, practice can become formal rather than living.

From a Jain point of view, the solution is not blame, but awareness and effort:

• daily navkār mantra
• samayik and pratikraman
• ahiṃsā in food and conduct
• study of Jain principles
• building strong Jain sangh and family habits

So, the issue is usually not that Jains “cannot” practice in the USA, but that the environment requires more conscious effort to preserve dharma.
