Actually, the enjoyment is in my mind. That is not enjoyment. That is not enjoyment. Real enjoyment is when I am free from this embodiment of five elements, gross elements, and three subtle elements. I have entered into this, and the action and reaction of these five gross elements, three subtle elements, I am enjoying. Actually, not enjoying. This is called māyā. There is no enjoyment. It is enjoyment in the mind. The mind is also material creation. Real enjoyment is beyond these senses. Sukham ātyantikaṁ yat tad atīndriya-grāhyam [Bg. 6.21]. That is stated in the Bhagavad-gītā: sukham ātyantikaṁ yat tat. The real happiness is not by these gross senses. By transcendental senses, we can enjoy sukham āt..., real happiness. Therefore, because we are not in that platform of enjoying the transcendental senses, we are trying to enjoy by these gross senses, therefore we are becoming baffled and frustrated. This is the cause of frustration. Because that is not the platform of enjoyment.
Sukham ātyantikaṁ yat tad atīndriya-grā... Atīndriya. Atīndriya means "beyond this." It is covered. Covered senses, you cannot enjoy. Suppose I cover your tongue with some cloth and then I give you one rasagullā. Can you taste it? What you'll taste? There are so many things. If you cover the senses, the real senses, and try to enjoy with that covering, what you'll enjoy? That is not enjoyment. The..., it has to be uncovered. Then you'll enjoy. That is indicated: sarvopādhi-vinirmuktaṁ tat-paratvena nirmalam [Cc. Madhya 19.170]. If you uncover the senses, upādhi... These upādhi... Because I am in bodily concept of life, therefore I am thinking, "I am American," "I am Indian," "I am Hindu," "I am Muslim," "I am black," "I am white," "I am man," "I am woman," "I am tree," "I am this," "I am that." This is covered. How you can enjoy with these covered senses?
So you have to uncover. You have to discover. That discovering process is devotional service. The more you are engaged in devotional service, the more your senses become pure or uncovered. And when it is completely uncovered, without any designation, then you are capable to serve Kṛṣṇa.
