udīcīṁ praviveśāśāṁ
gata-pūrvāṁ mahātmabhiḥ
hṛdi brahma paraṁ dhyāyan
nāvarteta yato gataḥ
He did not wait for his brothers (anaveksamanah). He decided to carry out the method taught by the Lord in man-mana bhava mad-bhaktah to attain Krsna in some solitary place, without disturbance, since he had now given up all responsibilities. This verse describes his action to achieve that. Param brahman means Krsna.
