"You should daven with a lot of kavannah."

"As we place renewed focus on this simple act, the following kavanah—intention—can become a moment of mindfulness and gratitude. Before washing hands or sanitizing, take a moment to pause and recognize what you’re doing" (source)

"I spent davening on my own, lost in thought, unworried about being judged for expressing too much kavanah, something I had to consider each morning in Minyan X." (source)

"It is through kavana that the sefirot become properly harmonized and united, allowing the Divine efflux to flow down, and the soul of the person practicing the kavana (called a "mechaven") becomes a channel through which G-d pours out His benevolence." (source)

"When we say these holy words, let us try to have kavana for what we are saying." (Glinert)
