त्रैविद्या मां सोमपाः पूतपापा यज्ञैरिष्ट्वा स्वर्गतिं प्रार्थयन्ते। ते पुण्यमासाद्य सुरेन्द्रलोक मश्नन्ति दिव्यान्दिवि देवभोगान् ॥

trai-vidyā māṁ soma-pāḥ pūta-pāpā yajñair iṣhṭvā svar-gatiṁ prārthayante te puṇyam āsādya surendra-lokam aśhnanti divyān divi deva-bhogān

The knowers of the three, the Soma-drinkers, the purified from sin, worshipping Me with sacrifice, pray of Me the way to heaven; they, ascending to the holy world of the Ruler of the Shining Ones, eat in heaven the divine feasts of the Shining Ones.

In plain words: Krishna says some people follow the three Vedas (holy books), drink the ritual drink called Soma, and offer sacrifices to ask for heaven. They go to the heaven of Indra, king of the gods, and enjoy heavenly pleasures there.
