Vajra Yoga

Vajra Yoga does not have seven chakra concept but emphasizes on only three chakras. In Vajra Yoga, chakras are primarily called Vajra Vayu Sthala. Muladhar Chakra, Swadhisthan Chakra and Manipura Chakra are referered with Naabhi Mula. Anahata Chakra and Vishuddha Chakra is Hridaya Mula and Agya Chakra and Sahastra Chakra is Trinetra Mula.

The most important experiment in Vajra Yoga is Vajra Vayu Dharana. In this holding the breath inside one does specific visualizations.

Vajroli Kriyas are also derived from Vajra Yoga.

Siddhas who know Vajra Vayu Chalana Kriya are able to transform their bodies into Vajra like strong bodies.

In Vajra Yoga, one emphasises a lot on Lalana Chakra which is a Upa Chakra or Laghu Chakra situated between Agya Chakra & Sahasrar Chakra. Vajra Nadi is also emphasised in Vajra Yoga.

Special meditation on light and  flames of lamps are also important part of Vajra Yoga.

Antaha Karana Shravan (observing inner sounds and activities) ,  focus on five senses and Prakriti Shravan (Observing nature around you and becoming engrossed in it) and studying various mental states and states of nature are all aspects of Vajra Yoga.
