Within Eckankar, HU is regarded as a sacred name for God, often described as a universal love song to the Divine and a key expression of the Sound Current or Audible Life Stream. It is pronounced like the word “hue,” usually as a long, drawn-out tone—“Huuuu”—and is understood to transcend any single religious tradition. Practitioners see this sound as a vibrational key that opens the heart, uplifts consciousness, and attunes the soul to the Light and Sound of God. In this sense, HU functions not merely as a word, but as a spiritual instrument intended to foster inner peace, divine love, and a more direct connection with the divine source.

In meditative practice, HU is used in a simple yet disciplined way. The practitioner typically sits comfortably with eyes closed, relaxes the body, and places gentle attention at the spiritual eye, the area between the eyebrows, or on a feeling of love for God. HU is then sung softly, often aloud but sometimes silently, in a long, sustained tone on the outgoing breath for about 10–20 minutes, though shorter periods are also common. The chant is offered in a loving, unforced manner, allowing the sound to resonate inwardly while thoughts are allowed to pass without attachment. After chanting, there is usually a period of quiet inner listening, during which one remains passively aware, attentive to subtle inner sound, inner light, images, or intuitive guidance.

Over time, this practice is believed to draw consciousness closer to the ECK, or Holy Spirit, and to the Sound Current itself. Many in the tradition regard HU as a central aid to Soul Travel, the conscious exploration of spiritual realms beyond the physical body, whether in meditation, dreams, or other inner experiences. It is also used for spiritual protection, clarity, and the opening of the heart to divine love, and thus becomes a daily spiritual exercise as well as a support in times of stress or the search for guidance. In group settings, HU may be chanted collectively, reinforcing its role as both a personal mantra and a shared act of worship aimed at God-Realization through direct spiritual experience.
