Hiding in plain sight
Sefer Tehillim is not just another volume in Tanach. The entire Torah is encapsulated in coded form within Tehillim.
Ideas that would take pages to fully explain are hiding behind one word or phrase, just waiting to be discovered. These ideas are hiding in plain sight on every page, yet we overlook them imagining that they only recount the travails King David was experiencing thousands of years ago.
With the knowledge that the words of Tehillim are essentially passwords that unlock hidden doorways, perhaps it would be more appropriate for us to read and contemplate a single kapitel 150 times a week rather than quickly reading through 150 kapitlach to complete the entire book in a week’s time.
I am not sure. Maybe both methods have their merit…
