So there is no difficulty to understand Kṛṣṇa. And if you understand Kṛṣṇa, your life is perfectly, I mean to say, all right. Then you get your life, complete perfection of your life. That is the whole literature. So here the Lord says, yas tu ātma-ratir eva syāt. Ātma-rati, one whose focus of life is simply for self-understanding... Ātma-ratiḥ, syād ātma-tṛptaś ca mānavaḥ. He is simply satisfied with his self-understanding, that "I am pure consciousness. My relation with Kṛṣṇa is such and such. My relation with this world is temporary. My real relation with Kṛṣṇa because Kṛṣṇa is permanent and I am permanent. I am His part and parcel," these simple things. So one who has understood these things nicely and he is satisfied in himself...
Just like Śukadeva Gosvāmī. He didn't care for anything, who is naked dancing, or naked bathing. No. He has no care. He is going on in the street. Yas tu ātma-ratir eva syād ātma-tṛptaś ca mānavaḥ ātmany eva ca santuṣṭaḥ. He is satisfied in himself and with Kṛṣṇa. Tasya kāryaṁ na vidyate: "He has nothing to do." Bas. He is free. Now, if you are not in that stage, then you have to perform sacrifice, as recommended in the Bhagavad-gītā. Yajñārthe karmaṇo 'nyatra loko 'yaṁ karma-bandhanaḥ (BG 3.9). You have to work in such a way that your work will be purified gradually and you will come to this stage of ātma-rati. But if you, from the very beginning, you are satisfied with your self-understanding, then you have nothing to do. You have nothing to do.
Just like ārādhito yadi haris tapasā tataḥ kiṁ nārādhito yadi haris tapasā tataḥ kim antar bahir yadi haris tapasā tataḥ kiṁ nāntar bahir yadi haris tapasā tataḥ kim. Tapasā tataḥ kim: (Nārada Pañcarātra) "What is the use of this nonsense penance and meditation? What is the use?" There is no more use. For whom? Now, ārādhito yadi hariḥ. Hari means the Supreme Personality of Godhead. If His relationship is completely understood and one is engaged in Him, then for him all these penances, meditation, and jñāna, yoga, all is nonsense. Nonsense means he has no requisition for all these things. He has come to the highest stage. Ārādhito yadi hariḥ.
And nārādhito yadi hariḥ. And after performing all these penances, and jñāna, yoga, meditation, ultimately end there is no understanding of Kṛṣṇa, then whole thing is spoiled. Tapasā tataḥ kim: "What is the use of all this nonsense if you have not understood the real thing?" If you understood the real thing, then also these things are nonsense. And if you have not understood the real thing, then these things are also nonsense.
