Happiness, of course, a hog also thinks that he is very happy that he is eating stool, and living in a filthy place, and because he has got the facility of sex life without any discrimination he may think happy life, but that is not happiness. Happiness is a different thing. Sukham ātyantikaṁ yat tad atīndriya-grāhyam (BG 6.21). If you want to feel happiness by these blunt material senses, that is not happiness. Happiness is beyond your material senses. Ātyantikam. That is real happiness. Real happiness means it will never end, and you will never feel satiation, that "I no more want." That is real happiness. Material happiness, there is no such thing. That you will feel immediately satiation. After enjoying any material happiness a few minutes, you will feel "Again another, again another, again another." So therefore in the Bhagavad-gītā it is said, sukham ātyantikaṁ yat tat (BG 6.21). So real, what is real happiness, that is not felt by these blunt material senses. So what is that sense? That is purified senses. Sarvopādhi-vinirmuktam tat-paratvena nirmalam (CC Madhya 19.170). When our senses are purified, for the sake of Kṛṣṇa, when our senses are employed for the sake of Kṛṣṇa, that is purified senses. Hṛṣīkeṇa hṛṣīkeśa-sevanaṁ bhaktir ucyate. That is wanted.
