Happy Tu B'Av, the Jewish holiday of love (think Valentine's Day without all of the Hallmark hoopla) that celebrates the feelings of our heart. In true Meshugena STEAM fashion, we say the heart is a core part of the human body, and from where we express and feel our most profound emotion.

The human heart is a muscular organ that pumps blood throughout the body via the circulatory system. It has four chambers: the right atrium and right ventricle, which receive deoxygenated blood and send it to the lungs, and the left atrium and left ventricle, which receive oxygenated blood and pump it to the rest of the body. Valves between chambers ensure one-way flow. The heart beats rhythmically, driven by electrical impulses from the sinoatrial node. This continuous circulation delivers oxygen and nutrients to tissues and removes waste. The heart’s efficiency and resilience make it central to sustaining life and the Core of our being.

The Torah begins with the letter Bet (ב) and ends with Lamed (ל)—together forming Lev, the Hebrew word for heart, tying the end of the Torah with beginning with heart. This is no accident. The sages teach that the Torah is not merely law, but the living heartbeat of creation. From beginning to end, it pulses with divine wisdom, compassion, and rhythm. To study Torah is to listen to the heart of God. And to live by it is to let that heart beat within us.
