Kṛṣṇa is sitting within your heart. Kṛṣṇa is the . . . is acting as your spiritual master, caitya-guru. Caitya-guru. Caitya-guru means the guru, or the spiritual master, who is sitting in my heart, citta. So śṛṇvatāṁ sva-kathāḥ kṛṣṇaḥ.
When you begin to hear about Kṛṣṇa, then the hearing of kṛṣṇa-kathā, the topics about Kṛṣṇa, is puṇya-śravaṇa-kīrtanaḥ. It is, even if you do not understand, it will increase your virtue. Puṇya-śravaṇa-kīrtanaḥ hṛdy antaḥ-stho hy abhadrāṇi. We have accumulated so much dust by our material contact. By so many years' association with the matter, we have accumulated so much dirty things within our heart. That becomes gradually cleansed. Śṛṇvatāṁ sva-kathāḥ kṛṣṇaḥ puṇya-śravaṇa-kīrtanaḥ, hṛdy antaḥ-stho hy abhadrāṇi. Hṛdy antaḥ-stho means the dirty things which we have accumulated within our heart, that becomes cleared.
That . . . how it is cleared? Hṛdy antaḥ-stho hy abhadrāṇi vidhunoti suhṛt satām. Śrī Kṛṣṇa is friend of everyone, but He's a special friend to the devotee. That you will find in Bhagavad-gītā. Samo 'haṁ sarva-bhūteṣu na me dveṣyo 'sti na priyaḥ (BG 9.29):
"I am friend of everyone. Nobody is My enemy and nobody is My friend. But I am equal to everyone." Sama, sama means equal. Ye tu bhajanti māṁ bhaktyā teṣu te mayi (BG 9.29): "But a person who is devoted to Me and is engaged in devotional service with Me, I have got special attention for him."
Therefore Kṛṣṇa's another name is suhṛt satām. Satām. Satām means those who are trying for having eternal life. Because in this material world we don't get anything eternal. All, everything, temporary. Therefore it is called asat. Asato mā sad gama. The Vedic injunction is, "Don't try to remain in this temporary world." Sad gama: "Just try to go to the eternal world." Tamaso mā jyotir gama: "Don't try to remain in this darkness. You go to the kingdom of light." These are Vedic injunctions.
So Kṛṣṇa, He is within our heart. Hṛdy antaḥ-sthaḥ. Therefore, as soon as we become a little inclined towards Kṛṣṇa, then from within our heart He gives us the, I mean to say, favorable instruction so that we can gradually make progress. Gradually.
