If you do little thing for the service of the Lord, it is noted in the notebook of Kṛṣṇa.
Don't think that your labor is going in vain. Whatever you do sincerely, that is noted. It is clearly stated here, teṣu te mayi: ""As they are always, constantly thinking of Me, similarly, I am also constantly thinking of how he can make further development, how he can come to Me very quickly, how he can be free from all contamination of the material . . ."" He will give you intelligence.
That is stated in another place. You will find in the Tenth Chapter, teṣāṁ satata-yuktānāṁ bhajatāṁ prīti-pūrvakam (BG 10.10): "Those persons who are always engaged in love and devotion in My service,"" buddhi-yogaṁ dadāmi tam, "I give them intelligence." Because intelligence required. A fool cannot make progress in Kṛṣṇa consciousness, only the intelligent person. And that intelligence is supplied by God.
