“So if you want to know the Absolute Supreme Personality of Godhead, you cannot speculate, neither meditate.
It is not possible, because your senses are very imperfect. So what is the way? Just hear from Him. So He has kindly come to say Bhagavad-gītā. Śrotavyaḥ: “Just try to hear.” Śrotavyaḥ and kīrtitavyaś ca. If you simply hear and hear in the class of Kṛṣṇa consciousness, and go outside and forget, oh, that will be not nice. That will not make you improve. Then, what is? Kīrtitavyaś ca: “Whatever you are hearing, you should say to others.” That is perfection.
…… Not only simply hearing. “Oh, I am hearing for millions of years; still, I cannot understand”—because you do not chant, you do not repeat what you have heard.
You have to repeat. Kīrtitavyaś ca. Śrotavyaḥ kīrtitavyaś ca dhyeyaḥ. And how can you write or how you can speak unless you think of Him? You are hearing about Kṛṣṇa; you have to think, then you can speak. Otherwise not. So śrotavyaḥ kīrtitavyaś ca dhyeyaḥ and pūjyaś ca. And you should worship. Therefore we require this Deity for worshiping. We have to think of, we have to speak, we have to hear, we have to worship, pūjyaś ca… Then? Occasionally? No. Nityasya: regularly. Regularly. Nityasya. This is the process.”
