PURPORT

The word udyana refers to places where trees are especially grown to produce fruits and flowers, which are most important for human civilization. Krsna says in Bhagavad-gita (9.26):

patram puspam phalam toyam
yo me bhaktya prayacchati
tad aham bhakty-upahrtam
asnami prayatatmanah

"If one offers Me with love and devotion a leaf, a flower, fruit or water, I will accept it." Fruits and flowers are very much pleasing to the Lord. If one wants to please the Supreme Personality of Godhead, he can simply offer fruits and flowers, and the Lord will be pleased to accept them. Our only duty is to please the Supreme Godhead (samsiddhir hari-tosanam). Whatever we do and whatever our occupation, our main purpose should be to please the Supreme Lord. All the paraphernalia mentioned in this verse is especially meant for the satisfaction of the Lord, not the satisfaction of one's senses. The government-indeed, the entire society-should be structured in such a way that everyone can be trained to satisfy the Supreme Personality of Godhead. But unfortunately, especially in this age, na te viduh svartha-gatim hi visnum: people do not know that the highest goal of human life is to please Lord Visnu. On the contrary, like demons, they simply plan to kill Visnu and be happy by sense gratification.
