The spiritual world needs no sun because Krishna's effulgence illuminates all existence with perfect knowledge and freedom.Listen — Srila Prabhupada Uvaca
Śrīmad-Bhāgavatam 3.28.21 — November 1, 1975, Nairobi 751101SB-NAIROBI [27:15 Minutes] SB-03.28.21_751101SB-NAIROBI Harikeśa: Translation: "The devotee should first concentrate his mind on the Lord's lotus feet, which are adorned with the marks of a thunderbolt, a goad, a banner and a lotus. The splendor of their beautiful ruby nails resembles the orbit of the moon and dispels the thick gloom of one's heart." Prabhupāda: Sañcintayed bhagavataś caraṇāravindam [SB 3.28.21]. This is the beginning of meditation, sañcintayet. It is not nirviśeṣa, nirakara meditation.
What is that meditation? Here it is, direction, sañcintayet. Sañcintayet means meditation. What about, meditation?
Sañcintayed bhagavataś caraṇāravindam. First of all meditate on the lotus feet, caraṇāravindam, lotus feet of Kṛṣṇa. And if you minutely see, then you will find the symptoms are there. Our feet and Kṛṣṇa's feet, there is difference.
Why difference? Because on the sole these marks are there. What is that? Vajra, aṅkuśa, dhvaja, saroruha.
Four things are there: thunderbolt, mark of thunderbolt; aṅkuśa, the mark of... What is that instrument which controls the elephant? Harikeśa: Driving rod?
Prabhupāda: No. It is called aṅkuśa in Sanskrit. It is like this. Harikeśa: Hook.
Prabhupāda: Maybe, whatever. So aṅkuśa. Vajra, thunderbolt; then aṅkuśa; then dhvaja, flag; and saroruha, lotus—these four things are there. You have seen.
