The Root Lock is done by inhaling deeply, holding your breath longer and then exerting muscular contraction and compression of the perineum and anus muscles. Afterwards the lock is released. This technique helps to activate the seat of the kundalini. The Kundalini energy is activated and pumped upwards. It is also utilised to compress the pranic and kundalini energy not to go downward during the compression period. This energy moves upward with greater force and intensity.
