बोधनात्स्वापनाच्चैव जगतो हर्षणं भवेत् ।अग्नीषोमकृतैरेवं कर्मभिः पाण्डुनन्दन ॥
In plain words
It is by waking the world and by laying it down in sleep that gladness comes to it — thus, son of Pāṇḍu, by the works of Agni and Soma.
Close to the Sanskrit
From the awakening and from the putting to sleep alone, a gladdening of the world would come about — thus, by actions performed by Agni and Soma, O son of Pāṇḍu.
