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.
