Viṣṇu-sahasranāma—Yudhiṣṭhira’s Inquiry and Bhīṣma’s Recitation (विष्णोर्नामसहस्रम्)
अल्पव्ययं महार्थ च प्रेत्य चैव सुखोदयम् । पानीयस्य गुणा दिव्या: प्रेतलोके विशेषत:
alpavyayaṁ mahārthaṁ ca pretya caiva sukhodayam | pānīyasya guṇā divyāḥ pretaloke viśeṣataḥ ||
Dijo Yama: «Este dharma exige un gasto muy pequeño, pero otorga un gran beneficio; y aun después de la muerte hace surgir la verdadera dicha. Las cualidades del agua son divinas, y en el reino de los difuntos se manifiestan con especial claridad».
यम उवाच
Even a modest act of dharma—here centered on providing water—can produce immense spiritual benefit, including happiness after death; water is portrayed as inherently sacred and especially efficacious for the welfare of beings in the preta-loka.
Yama, the lord of dharma and the dead, is explaining the fruit of a particular righteous practice: offering/providing water. He emphasizes its low material cost, high moral-spiritual return, and its special significance for the departed.
