हरिरेकः सदा ध्येयो भवद्भिः सत्त्वसंस्थितैः ।ओमित्येवं सदा विप्राः पठत ध्यात केशवम् ॥
In plain words
Hari alone, always — he is the one you are to meditate on, you who stand steady in sattva. So: Om. Say it just so, always, brāhmaṇas — recite it, and hold Keśava in your mind.
Close to the Sanskrit
Hari alone is always to be meditated upon by you who are firmly established in sattva. 'Om' — thus, always, O brāhmaṇas, recite; meditate upon Keśava.
