Mula Bandha, often referred to as the "root lock," is a foundational technique within Hatha Yoga. This practice is considered a primary bandha, or body lock, and is crucial for controlling vital energy
within the body. Its Sanskrit name, Mula Bandha, translates to "root lock," emphasizing its connection to the base of the spine and the pelvic floor. The technique is designed to prevent the leakage of life energy, known as prana, and to direct it upwards through the central energy channel, the sushumna.
Understanding Bandhas and Their Purpose
In Hatha Yoga, bandhas are internal mudras, or body locks, that serve to contain and direct vital energy. The concept of a bandha is to create a synergy between yoga postures and breathing techniques. This interplay aims to gather and utilize bundled quantities of prana, or life energy. Mula Bandha is particularly significant as it is seen as the first and most important bandha, essential for safe and grounded meditative practices. It is believed to maintain the muladhara chakra in good condition, which is the root chakra associated with stability and grounding.
The action of bandhas and mudras is intended to capture energetic fluids such as breath, prana, bindu, and amrita, thereby assisting in unblocking the central channel, Sushumna. The term "bandha" itself literally means bond, fetter, or grip, highlighting its function in securing and controlling energy. While Mula Bandha focuses on the perineum, other bandhas exist, such as Uddiyana bandha (abdominal contraction) and Jalandhara Bandha (chin lock). The combination of all three is known as Maha Bandha, or the "great lock."
Physiological and Energetic Mechanisms
Mula Bandha is defined as the sealing of the source, with this source being the root of the spine, specifically the center of the pelvic floor, or the perineum. The perineum is the muscular area located between the anus and the genitals. The technique involves a slight contraction of the pubo-coccygeal (PC) muscle, which extends from the pubic bone to the tailbone (coccyx). This contraction creates an energetic seal that is said to lock prana into the body, preventing its escape from the base of the spine.
According to yogi B.K.S. Iyengar, Mula Bandha involves contracting and lifting the muscle that runs from the anus to the navel along the spine. He clarifies that this contraction is not of the sphincter or urinary muscles, but rather the muscle situated between them. Swami Buddhananda identifies this specific area as the perineal body. The practice is described as similar to a Kegel exercise, focusing on the subtle engagement of these deep pelvic floor muscles. The goal is to move prana into the sushumna, the subtle equivalent of the spine, thereby awakening the Kundalini energy.
Historical Context and Awakening Kundalini
The earliest textual mention of Mula Bandha dates back to the 12th-century text, Gorakṣaśataka. This ancient text defines Mula Bandha as a yogic technique aimed at achieving mastery of breath and awakening the goddess Kundalini. It describes how the yogi forces the downward-moving apāna breath upwards through contraction. This action, known as Mula Bandha, causes apāna to reach the "orb of fire," intensifying the flame. This fanned flame then rises, causing fire and apāna to unite with prāṇa, which is inherently hot. The resulting blaze within the body heats and awakens the sleeping Kundalini.
The text vividly portrays Kundalini's awakening: "Like a snake struck by a stick, she hisses and straightens herself. As if entering a snake-hole, she enters the Brahmā nāḍi." This emphasizes the profound energetic transformation believed to occur through consistent practice of Mula Bandha. Iyengar further explains that Mula Bandha makes Apāna Vāyu, the prāṇa in the lower abdomen that naturally moves downwards, flow upwards to merge with Prāṇa Vāyu, which resides in the chest. He suggests that Mula Bandha should initially be attempted during antara kumbhaka, which is the retention of breath after inhalation. Through this practice, the yogi endeavors to connect with the true source, or mūla, of creation.
