With the counting of sefiras haomer, we are celebrating the switch from harvesting barley... to harvesting wheat.
Barley is coarse animal food. It represents animalistic traits. Everyone can be an animal with no effort. Eating, lusting, sleeping, etc. are all animalistic traits.
Wheat produces bread, which is food for humans. This represents the traits of a mentch; pushing aside our animalistic desires, and replacing them with seichel and proper middos.
Sefirah is a time where we evolve from our selfish, animalistic selves, into proper, well mannered, functioning, G-d fearing human beings.
Let's use this auspicious time to grow and evolve into who we really are.
