Perceived through the mudras of

Karankini, krodhana, bhairavi, lelihanaya, and khechari

Illuminates Shiva realization

Mudras, or gestures, as commonly understood in yoga, are hand posture that complement asanas, physical postures and pranayama, breath control, as part of the external or bahiranga yoga practices. Mudras complete the energy circuit of the body in different ways. Each finger of the hand represents different elements of energy, such as space, air, fire, water and when brought together in different finger combinations and different levels of the body and different postures, theses mudras induce different energy levels. Mudras in yoga and in classical dance forms are quite different, the later generally representing emotions.

Having said that, I do wish to record that in experimenting with mudras, I found a strong connection with chakras,  which in turn connect to emotional states. I found that with different mudras my breathing shifted from chakra to chakra. When I taught this to others I found it worked the same way.

In this verse, Shiva refers to five mudras that lead to realization of the ultimate reality. You will find references to these mudras in yoga related internet sites. I do not wish to go into details of these since these need to be learnt and practiced under expert supervision. Karankini for detachment, krodhana to manage emotions, bhairavi for inner awareness, lelihanaya for consciousness, and khechari for bliss are powerful mudras that are part of the tantric process of raising the kundalini energy. http://www.swamij.com/hatha-yoga-pradipika.htm#chapter3 provides details on some of these. They are not do it yourself practices.

Mudras heal body, mind and spirit. Simpler mudras such as chin mudra, prana mudra, and prithvi mudra can be safely practised as part of one’s meditation practice. Books from Bihar School of Yoga are probably the best resources.
