Teṣāṁ satata-yuktānāṁ bhajatāṁ prīti-pūrvakam (BG 10.10). Those who are twenty-four hours engaged in the devotional service—not as a routine, but with faith and love—bhajatāṁ prīti-pūrvakam. Not that official. Official, he cannot understand. But one who is serving the Deity with love and faith, to him only, Kṛṣṇa will reveal, and He will give intelligence. Kṛṣṇa is very intelligent. Kṛṣṇa ye bhaje . . . only intelligent men can worship Kṛṣṇa.
So here it is said, yaṁ vai na gobhir manasāsubhir vā hṛdā girā vāsu-bhṛto vicakṣate. Tan māyā-mohitād na jānanty ity uktam, avaśed tata tasya ityāhayam iti. Gobhir indriyair cittena na vicakṣata na paśyanti. So gobhiḥ, by sensual gymnastic or mental speculation, the Supreme Personality of Godhead cannot be understood. There are many mental speculator, just like Aurobindo Ghosh. So he speculated.
He understood that there are activities even after liberation, but he could not understand Kṛṣṇa, so hard it is. Others, the so-called sannyāsīs, just like Ramatirtha or Vivekananda, they could not approach even, in the modern age. And the Aurobindo, he approached up to the Brahman liberation, but he could not approach to the understanding of the Supreme Personality of Godhead.
That is . . . Arjuna says also in the Bhagavad-gītā, "It is very difficult to understand Your personality." Everyone becomes . . . the other day in the Melā, Māgha-melā, one Gangeshvarananda, retired high-court judge, he said that, "This is the first time, Swāmījī, that we are hearing from you on solid basis about the Personality." The whole world, nirviśeṣa-śūnyavādi . . . nirviśeṣa . . . means the impersonalists and voidists, that's all. They have no understanding what is Personality of Godhead.
