There are a total of six Kriyas known as Shat Kriyas. These six types of Kriya yoga extensively clean out the internal organs, allowing a smoother flow of life force energy (pranic flow) among the two major energy centres, Ida and Pingala. This purification process will help you attain mental and physical balance with regular practice of Kriya yoga.
The following is a detailed description of the types of Kriya yoga:
1. Kapalabhati
The name Kapalabhati is derived from Sanskrit. “Kapala” means “skull”, and “bhati” means “shine“. This process helps to cleanse your lungs and energise the frontal lobe of your brain.
Steps to Do:
Step 1: Inhale deeply upto your navel.
Step 2: Exhale 3-4 times.

2. Neti
Neti in Sanskrit refers to the process of nasal cleansing. This process helps to clear out the nostrils. There are multiple mediums incorporated in this process, like water, ghee, milk or the help of a wax thread. The origins of this cleansing practice can be traced back to 5000 years ago when other processes like shatkarma (body cleansing) and soucha (personal hygiene) came into practice.
