Kriya yoga is all about spiritual growth. Through meditation, it helps create awareness and self-consciousness. Continuous practice of Kriya yoga can accelerate a person’s pace to meet his/her higher self. The phrase Kriya yoga means ‘yoga of action’. Discipline comes first and foremost in this practice.

Kriya yoga can only assist you in finding the proper connection with your divine self; discipline will help you attain it. Munis and Yogis have been suggesting kriya yoga techniques to clean out the toxins that have accumulated internally. Read further to know what Kriya yoga is and its six processes of cleansing your system from within.

Kriya Yoga is an ages-old, profound technique of spiritual realization founded upon the teachings of the ancients about self-realization. This exacting spiritual discipline seeks development according to precise techniques in breath control, meditation, and inner purification.

Kriya Yoga cleanses man's nervous system systematically, quiets the mind, and thus awakens that dormant spiritual power within one to guide him toward self-realisation and a balanced, enlightened life.

Kriya is an ancient yoga technique that remained a secret for a long time but was revived in 1861. The revival took place when Lahiri Mahasaya met the eminent yogi Mahavatar Babaji in the Himalayas. Mahavatar Babaji taught Kriya Yoga to Lahiri Mahasaya, who went on to become his disciple.

Lahiri Mahasaya mastered and spelled out the principles of Kriya Yoga, propagating it with great emphasis on advanced techniques for spiritual growth and self-realisation. This revival played an important role in bringing Kriya Yoga to the masses.

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:

Before commencing Kriya Yoga, one should be aware of the precautions that need to be taken to carry it out safely and effectively.

Though the preferable time for Kriya Yoga varies according to the personal liking and daily routine of the practitioner, excellent times are found to be:

• Early Morning: Practising Kriya Yoga before sunrise in the early morning is recommended by most teachers. This is also the best time to start the day with a clear, focused mind.
• Before Meals: Kriya yoga is done so that the stomach remains empty, or at least a couple of hours should pass after eating, as it causes discomfort to the practitioners, so they may not remain focused.
• Regular Timing: Have one particular time of practice, which helps set a routine so it is easy to fit Kriya Yoga into one's life. Follow that time every day so your body gets used to the timing.
• Quiet and Calm Periods: Set an advanced time for practising where one can be in silence and tranquillity without being bothered, which will be one good option for practising.

The best time is when you can practise regularly and remain consistent with your path and lifestyle.

Kriya yoga is undoubtedly the best practice that one can take up to help oneself feel better and do better in one's life. However, the only thing that must be kept in mind is choosing the right Guru. They must be qualified and have a great amount of experience in this field to help others. Anyone can practise Kriya yoga techniques to lead a healthier lifestyle.
