These four verses are recognized as the chatuh-shloki Bhagavad Gita, or the set of four verses summarizing the whole Bhagavad Gita. It has three parts – understanding of our loving relationship with God, acting in that loving relationship, and receiving love and enlightenment back from God.
Krishna explained in the previous section how He is the source of everything and everyone – the various states of our existence, the demigods, the sages, the progenitors, as well as their descendants.
Put more emphatically, Krishna (ahaṁ) is the source (prabhavo) of all spiritual and material worlds (sarvasya), and from Krishna (mattaḥ), emanates (pravartate) everything (sarvaṁ). What happens when one discovers Krishna as the source of one’s existence? The wise (budhā) who realize this (matvā) engage in the devotional service (bhajante) of Krishna (māṁ) filled with loving feelings (bhāva-samanvitāḥ). (BG 10.8) These loving feelings are accompanied by commensurate actions. Their thoughts dwell in Krishna (mac-cittā), their lives are fully devoted to Krishna’s service (mad-gata-prāṇā), and they derive great satisfaction (tuṣyanti ca) and bliss (ramanti ca) from always (nityaṁ) enlightening one another (bodhayantaḥ parasparam) and conversing (kathayantaś) about Krishna. (BG 10.9)
How does Krishna reciprocate with such a soul? To those who are thus constantly connecting with Krishna in love (teṣāṁ satata-yuktānāṁ), Krishna gives (dadāmi) the yoga of intelligence (buddhi-yogaṁ) by which they can come back to Krishna (yena mām upayānti te). (BG 10.10) Note that going back to Krishna or Krishna’s abode is maintained as a goal in whatever we receive from Krishna. For them alone (teṣām eva), to give them special mercy (anukampārtham), Krishna (aham) from within (ātma-bhāva-stho) destroys (nāśayāmy) the darkness born of ignorance (ajñāna-jaṁ tamaḥ) with the shining lamp of knowledge (jñāna-dīpena bhāsvatā). (BG 10.11)
Arjuna will reveal next how the enlightened conditions look like from his perspective.
