Srimad-Bhagavatam: Canto 4 - Chapter 1 - Verse 4
तमागतं त उत्थाय प्रणिपत्याभिनन्द्य च ।पूजयित्वा यथादेशं सुखासीनमथाब्रुवन् ॥ ४ ॥
tam āgataṁ ta utthāyapraṇipatyābhinandya capūjayitvā yathādeśaṁsukhāsīnam athābruvan
As soon as the Pracetās saw that the great sage Nārada had appeared, they immediately got up even from their āsanas. As required, they immediately offered obeisances and worshiped him, and when they saw that Nārada Muni was properly seated, they began to ask him questions.
It is significant that all the Pracetās were engaged in practicing yoga to concentrate their minds on the Supreme Personality of Godhead.
