yuñjann evaṁ sadātmānaṁ
yuñjan — practicing; evam — as mentioned above; sadā — constantly; ātmānam — body, mind and soul; yogī — the mystic transcendentalist; niyata-mānasaḥ — with a regulated mind; śāntim — peace; nirvāṇa-paramām — cessation of material existence; mat-saṁsthām — the spiritual sky (the kingdom of God); adhigacchati — does attain.
Thus practicing constant control of the body, mind and activities, the mystic transcendentalist, his mind regulated, attains to the kingdom of God [or the abode of Kṛṣṇa] by cessation of material existence.
