Vajrasana is an Indian translation for Thunderbolt pose. Vajrasana is an important meditation posture so as to give the body an upright and straight posture without any extra effort. This asana is even employed among Muslims and Zen Buddhists as prayer and meditational posture. One who finds Padmasana or Siddhasana uncomfortable may practice Vajrasana for meditational purposes. In this asana, the vital breath (prana) flows from Muladhara to Sahasrahdhara which helps in  meditation. It stimulates the vajra nadi, activates prana in shushumna and redirects sexual energy to the brain for spiritual purposes. There is no time limit for the practice of this asana. Practice this particularly after meal, for at least 5 minutes to enhance the digestive system. During the acute digestive disorder, practice abdominal breathing in this asana for 100 breaths before and after meals. You can learn this asana below:

Variation I:

• Get in the Vajrasana pose as aforementioned.
• Block breathing flow through nostrils.
• Place the left or right big toe over each other.
• This depends on the predominant air flow via left or right nostril.

• Eventually this helps in tranquilizing the mind.
