Bahu puna kera likely conveys “to perform many meritorious deeds” (bahu punya karā). In Jainism, punya means merits earned through virtuous conduct such as ahimsa (non-violence), satya (truth), brahmacharya, charity, and compassionate actions. Merits (punya) affect one’s karmic balance and help progress on the path to liberation.

Key points in Jain understanding:

• Punya is earned by wholesome actions that align with Jain values and restraint.
• Punya, along with papa (demerits), shapes the soul’s future experiences and reincarnations.
• The impact of punya can be influenced by intention (samyak bhav) and the overall spiritual discipline of the practitioner.
• Differences between Digambar and Shwetambar traditions may exist in ritual details, but the basic concept of punya as positive karmic merit is shared.

If you were asking about a specific mantra, verse, or text that contains the exact phrase, please provide the precise spelling or source, and I’ll explain its arth (meaning) and how it is understood in Digambara vs. Śvetāmbara paths.

Note: I can only answer questions in the Jain Dharma framework. If you want a more precise source or canonical wording, tell me the exact text you have in mind.
