Srila Prabhupada
When you see flower, you see Kṛṣṇa smiling. That is the seeing of Kṛṣṇa smiling. Therefore the flower should be utilized for Kṛṣṇa's service. Because these flowers, everything, is Kṛṣṇa's energy. Parāsya śaktir vividhaiva śrūyate (CC Madhya 13.65, purport). So specifically good fragrance of flower, Kṛṣṇa says that “I am that.” Kṛṣṇa’s particular presence is there. So we can remember Kṛṣṇa immediately. This Kṛṣṇa consciousness movement is that you remember always Kṛṣṇa. Always Kṛṣṇa.

Just like a small seed in a fruit—that seed you sow, it becomes a big tree. And from that big tree, again millions of fruits come out. And again from that, each fruit, there are millions of trees. We can see the potency. Even in our material existence we see so much potencies in everything. Why not Kṛṣṇa's potencies?

"Variety is the mother of enjoyment." Enjoyment. Ānanda means enjoyment. Enjoyment cannot be impersonal; there must be varieties. That is enjoyment. You have got experience that when there is a bunch of flower of different colors, it is very enjoyable. And if there is only rose only, although rose is very nice flower, it is not so pleasing. With rose, some green foliage, some grass, inferior quality, it looks very beautiful.
So when there is question ānanda . . . because Kṛṣṇa has got form, sac-cid-ānanda-vigraha (Bs. 5.1), eternal; cit, full of knowledge; and full of ānanda, bliss. Ānandamayo 'bhyāsāt, Vedānta-sūtra says. The Lord is ānanda-mayo.

Take for example the leaves of the tree. Some of them are green; some of them are red; some of them are yellow; some of them are mixed. Similarly fruits—different tastes; flowers—different flavor. Varieties. But wherefrom it is coming? The sunshine. The sunshine is the same, but it is acting in different way, so we see different manifestation. This is crude material example. Similarly, if we take the spiritual original, then the original is Kṛṣṇa. Kṛṣṇa says in the Bhagavad-gītā, ahaṁ sarvasya prabhavaḥ (BG 10.8). It is not different from Kṛṣṇa. Ahaṁ sarvasya. All these colored manifestation, it is coming from Kṛṣṇa. Mattaḥ sarvaṁ pravartate: "Everything is coming from Me." So this understanding is real Kṛṣṇa consciousness, when you understand that there is one only. Eka brahma dvitīya nāsti. And Kṛṣṇa is above Brahman. We have got a slight idea of Brahman, generally, but Kṛṣṇa is Paraṁbrahman. There are many millions of Brahmans, and above them, the Supreme Brahman is Kṛṣṇa. Paraṁ brahma paraṁ dhāma pavitraṁ paramaṁ bhavān (BG 10.12).
