श्री शंकराचार्य - कुमतेः पुरुषाधमस्य

लुब्ध्वा सुदुर्लभतरं नरजन्म जंतुः
    तत्रापि पौरुषमतः सदसद्विवेकम् ।
संप्राप्य चैहिकसुखाभिरतो यदि स्यात्
    धिक् तस्य जन्म कुमतेः पुरुषाधमस्य ॥

- श्री शंकराचार्य

lubdhvA sudurlabhataram nara janma jantu
    tatrApi pauruShamataH sat asat vivekam ।
samprApya cha aihika sukhAbhirato yadi syAt
    dhik tasya janma kumateH puruSha adhamasya ॥

- shri shankarAchArya

After having got the rare (and most sought after) human birth, and been rewarded with courage and wisdom to judge right and wrong if you still indulge in all the material pleasures then such a bad person with bad mind will be damned.

- Sri Shankaracharya
