The Hebrew word for "air" or "spirit," רוּחַ (Ruach), is composed of three letters: Resh (ר), Vav (ו), and Chet (ח). Each of these letters carries deep spiritual symbolism, particularly in the context of Ruach as the spirit and breath of life.

1. Resh (ר): The Head and Beginning
Resh is the 20th letter of the Hebrew alphabet and is often associated with the concept of the "head" or "beginning." It symbolizes leadership, authority, and the human mind.
Spiritually, Resh represents the beginning of consciousness and awareness, the initial spark of life that comes with the breath of life. In the context of Ruach, Resh points to the origin of life, the divine breath that initiates and sustains all living beings.
Resh can also symbolize the idea of returning or repentance (Teshuvah), indicating the cyclical nature of life and spirit—where the breath of life comes from God and ultimately returns to Him.
