So Kṛṣṇa consciousness is so nice that naturally it will make you beautiful—not black-faced, not morose—beautiful face. That is the sign of spiritual advancement. By the face you'll understand that, "Here is a man who is spiritually advanced." Pratyakṣam avagamaṁ dharmyam (BG 9.2). This process of spiritual consciousness can be directly perceived.
It is not theoretical, "Oh, I am a very great devotee." No. Simply theoretical understanding, "I am a great devotee . . ." From the very face it will be understood. Face is the index of mind, how you are thinking. If you are thinking of Kṛṣṇa always, then your face will be beautiful. Therefore it is called pratyakṣam avagamaṁ dharmyam, direct perception. There is no theoretical. It is practical. Pratyakṣyam avagamaṁ dharmyaṁ su-sukham.
Then to become such spiritually advanced, is it very difficult task? No. Su-sukham: very easily and very happy. How it is happy? Happy because this spiritual consciousness is developed by chanting Hare Kṛṣṇa mantra. That is very pleasing. With music, with musical instrument we chant Hare Kṛṣṇa mantra. There is no trouble. Even a child can take part, experience. A child also claps; he also dances. So what can be easier method than this?
Any other method you take, you have to exercise, you have to tax your brain, press your nose, or so many other things. But here automatically you chant before ārātrika and you become spiritually enlightened. Even the child becomes. Therefore it is susukham, very happy to execute. Susukham kartum avyayam (BG 9.2). And whatever you do, little, that becomes a permanent asset, avyayam. It is never to be vanished. Even one percent of devotional service you execute, it will help you again to begin from that point.
So here is a description of the Vaikuṇṭha-puruṣā. Sarve padma-palāśākṣāḥ (SB 6.1.34): "Your eyes are so beautiful, just like petals of the lotus flower." And pīta-kauśeya-vāsasaḥ: saffron and yellow, these two kinds of colors of garments, because . . . those who are Māyāvādīs, impersonalists, they cannot understand that there is another, spiritual world and there are spiritual planets, and their inhabitants, their bodily features are like this, their dress are like . . . everything is there. But unfortunate persons, they cannot understand. They think everything is here.
