Bhaupurra labam
It appears you may be referring to Bahu Putra Labham (blessing of progeny/children) or Bahu Phala Labham (attaining abundant fruits/merit), terms commonly found in the Phalashruti of Vedic chants and stotras.
In Vedic traditions, the concept of spiritual and worldly gain is structured through specific principles:
1. The Concept of Phalashruti
At the conclusion of sacred hymns (such as the Vishnu Sahasranama or Vedic suktas), a Phalashruti (phala meaning "fruit" and shruti meaning "hearing") is recited. It enumerates the benefits accrued by chanting or listening with pure devotion:
- Arogya Labham: Gain of health and freedom from disease.
- Dhana-Dhanya Labham: Gain of wealth, sustenance, and prosperity.
- Putra Labham: Blessing of righteous progeny to continue the family lineage and uphold Dharma.
2. Rituals for Progeny and Auspicious Gains
When referring specifically to the blessing of children (Putra Labham):
- Mantra: Chanting of the Santana Gopala Mantra or verses from the Rigveda invoking divine grace for healthy offspring.
- Kriya: Performing observances such as Santana Gopala Vratam or historical fire ceremonies like the Putrakameshti Yajna.
- Artha: Children in the Vedic worldview are not merely family additions, but carriers of the family's spiritual heritage who help fulfill the sacred debt to ancestors (Pitru Rina).
- Tattva: At the highest level, the true "gain" (Labha) in Vedic philosophy is the realization of the Atman, which brings freedom from the cycle of birth and rebirth (Moksha).
If you had a slightly different term or context in mind (such as a specific astrological house like Labha Bhava), please clarify so we can explore its precise Vedic meaning.
