Muladhara chakra is in the lower end of the Spinal Column. There resides the power Kundalini Coiled up. There are two nerve currents, Ida and Pingala, along the spinal column and hollow canal, Susumna, in the middle. When the kundalini awakes, it goes up through Susumna, step by step through various energy centres called chakras and finally reaches the brain centre or Sahasrara.

The technique given in this Upanishad is Kundalini Yoga technique involving hatha yoga and Pranayama.
The first step is Press the anus. That means the yogi should establish Mula-bandha. Contraction of muscles around perineum in the male or Cervix in the female is called Mula-bandha or Perineal Lock.
The second step is Force the vital air upward. The Yogi should do Uddiyana Bandha and Mula-bandha concurrently. By doing so the vital airs, Prana and Apana will go upward. Uddiyana Bandha is the contraction of the lower abdomen.
The third step is Circumambulate the Swathistana thrice. This means make Nauli Chalana thrice as if rounding the chakra thrice.
The next step is to reach Manipura, go beyond Anahata and hold the Prana under control in Visuddhi. Hold the Prana under control in Visuddhi means perform Jalandhra Bandha. The neck lock. It is evident that the steps indirectly meant Maha Bandha. Maha Bandha is the combination of three Bandhas.
The next step is reaching Anja, meditate on tri matra Turya at Sahasrara. Meditate on “A”, “U” and “M” as Turya. Turya Means ‘fourth’ state of consciousness. The four states of consciousness are wakeful, dream, deep sleep and Turya or being with Self. This meditation will be correctly understood when we study the other Upanishads later.
