After inspiring us to take exclusive (ananyāś) shelter of Krishna by contrasting with the demigod worship, Krishna now explains how easy it is to take shelter of Krishna and how He reciprocates with our efforts. This is one of the top mysteries revealed in this chapter.

Engaging in the loving devotional service of Krishna (bhakti yoga) is so easy that anyone can do it. If one offers (prayacchati) Krishna (me) with love and devotion (bhaktyā) a leaf (patraṁ), a flower (puṣpaṁ), a fruit (phalaṁ), or water (toyaṁ), He (ahaṁ) will accept (aśnāmi) that devoted gift (bhakty-upahṛtam) from a dedicated soul (prayatātmanaḥ). (BG 9.26) Krishna generalizes this principle and requests us to apply it to all our actions. Whatever we do (yat karoṣi), whatever we eat (yad aśnāsi), whatever we sacrifice (yaj juhoṣi), whatever we gift (dadāsi yat), and whatever austerities we perform (yat tapasyasi), we should do that (tat kuruṣva) as an offering to Krishna (mad-arpaṇam). (BG 9.27) In this way (evaṁ), we will be freed from (mokṣyase) bondage to work (karma-bandhanaiḥ) and its auspicious and inauspicious results (śubhāśubha-phalair). As a liberated soul (vimukto) connected in the spirit of renunciation (sannyāsa-yoga-yuktātmā), we will attain (upaiṣyasi) Krishna (mām). (BG 9.28)

Krishna is equally disposed (samo ’haṁ) toward everyone (sarva-bhūteṣu) – He neither hates (na me dveṣyo) nor favors anyone (’sti na priyaḥ). However (tu), those who render loving service (ye bhajanti) unto Krishna (māṁ) with devotion (bhaktyā) are transcendentally situated in Krishna (mayi te), and indeed (cāpy) reciprocally Krishna (aham) is transcendentally situated in them (teṣu). (BG 9.29) Thus, Krishna reveals His partiality toward His devotees. Even though as the Supersoul residing within everyone’s heart Krishna is neutral toward everyone, His presence is vividly manifest in His devotees in a personal way.
