In plain words
The Gītā also declares that if, instead, people act against God's command, or against the dharmas taught in the śāstra, which is the Lord's own decree, then even though they have deep Prema and faith in God, they are not devotees.
That is the meaning of Kṛṣṇa's words, “He who is full of Bhakti is dear to Me.” He declares further that, whatever karmas the devotee performs, he must not regard them as “my karma”; they must be the karma of Īśvara. People, that is, regard some karmas as their own and others as God's. To regard them so is not the mark of a devotee. If all karmas are regarded as karmas offered to God, they do not fall into abhimāna and mamakāra. The sādhana that roots out mamakāra and abhimāna is Bhakti. Everything must be regarded as filled with God.
అట్లు కాక భగవంతునియందు గాఢమగు ప్రేమ విశ్వాసములుండియు, భగవదాజ్ఞకు విరుద్ధముగా కానీ, లేక భగవానుని శాసనమైన శాస్త్రమునందు తెలుపబడిన ధర్మములకు విరుద్ధముగా కానీ ప్రవర్తించిన, అట్టివారు భక్తులు కారని కూడనూ తెలుపుచున్నది గీత.
