Kokinshu 1008 - "When Spring Arrives"

1008 When spring arrives And fields begin to bloom If you see a flower That’s just a sprout Mere whispers are best Until it’s out
春さればのべにまづさく見れどあかぬ花まひなしにただなのるべき花のななれや	Haru sareba Nobe ni mazu saku Miredo akanu hana Mainashi ni Tada nanoru beki Hana no na nare ya

Author unknown. A reply to a poem #1007. He says that when love is new, it's best to proceed gently until the flower is in full bloom.
