ORDER AND CATEGORIES OF MUDRAS
Mudras are usually listed in no particular order, which makes the understanding of the whole category of mudra difficult. There have been attempts to define groups of mudras through their location applied, such as hands, head, postural, pelvic, etc. I worked with this method for a while and found it unsatisfying because the location does not say much about the function. I then looked into ordering mudras according to function. This would lead us to the groups of bandhas (energetic locks), mudras that are combinations of posture, bandhas and kumbhaka, mudras engendering longevity, those associated with increasing strength, mudras designed to raise Kundalini, and mudras designed to trigger samadhi. The order would then look like this:
Mula Bandha, Uddiyana Bandha, Jalandhara Bandha, Jihva Bandha, Maha Bandha
2. Mudras that are combinations of posture, bandha and kumbhaka:
Yoga Mudra, Tadagi Mudra, Maha Mudra, Maha Bandha Mudra, Maha Vedha Mudra, Kaki Mudra, Vajroni Mudra, Shanmukhi Mudra, Shakti Chalana Mudra, Matsyendra Mudra
- Mudras promoting longevity:
Tadaga Mudra, Viparita Karani Mudra, Ashvini Mudra, Manduka Mudra, Bhujangi Mudra, Vajroli Mudra, Matanga Mudra, Maha Mudra, Kaki Mudra
4. Mudras for raising Kundalini
Khechari Mudra, Pashini Mudra, Ashvini Mudra, Bhujangi Mudra, Vajroni Mudra, Vajroli Mudra, Shakti Chalana Mudra
- Mudras creating strength:
Matangi Mudra, Pashini Mudra, Vajroni Mudra
6. Meditation and samadhi mudras
Shambhavi Mudra, Shanmukhi Mudra, Jyoti Mudra, Bhramari Mudra, Khechari Mudra
The problem with this approach is that it makes mudras in one group lacking connection with each other. The categories of strength, longevity, meditation, bandhas, combination of…, etc. are from different levels of structural hierarchy. Many mudras need to appear in several categories, which makes the above table clumsy. To find a solution to systematize mudras, we need to hark back to the Yoga Sutra. Patanjali, the author of the Sutras, ordered limbs according to function and outcome. And that is exactly why he didn’t treat mudras as a separate limb. The function and outcome of the mudras are already explained through their association with the limbs. There are mudras primarily related to asana, pranayama, pratyahara, dharana and samadhi. Primarily here means they can have aspects related to several other limbs, but usually, the mudra‘s primary function is easily discernible. That easily discernible primary function determined the order in which I have presented the mudras here. The view that mudras are allocated to certain limbs is corroborated by Hatha Yoga Samhita which states that mudras are techniques that support practices like pranayama, pratyahara, dharana, dhyana and samadhi . These are the categories in which I have ordered the mudras, with omitting dhyana because I could find only one mudra primarily relating to dhyana, even then not clearly.
Here then are the categories and their allocated mudras:
1. Asana Mudras
These mudras are primarily pranic (this anglicized term means energetic or related to life-force) modifications of asanas and are inserted into one’s existing asana practice. Mudras in this group include Tadaga-, Viparita Karani-, Vajroni-, and Yoga Mudras. Alternatively, they are techniques whose purpose, similar to asana, is primarily to strengthen the body and increase health and longevity, such as Nabho-, Matsyendra-, Bhujangi-, Manduka-, and Matangi Mudras. The purpose of this group is the sthirata (fortitude) of the Gheranda Samhita, which was also T. Krishnamacharya’s focus. Authorities who believed this group of mudras to be the quintessential one concluded that mudras should be practised before pranayama.
2. Pranayama Mudras
In this group, you will find mudras primarily associated with the limb of pranayama or they are ancillaries to pranayama. These are Mula-, Uddiyana-, and Jalandhara Bandhas, as well as Shanka-, and Kaki Mudras.
3. Pratyahara Mudras
Pratyahara, the fifth limb of yoga, is often translated as sense-withdrawal, but it is better understood as independence from external (sensory) stimulus. The mudras in this group are primarily designed to project sensory prana (prana that powers the various senses, such as audio, visual, etc.) back into the body, therefore making us independent from sensory stimulus. These include Jihva Bandha, Shambhavi-, Akasha-, Jnana-, Agochari-, and Dhyana Mudras. Two special cases here are Shambhavi-, and Dhyana Mudras. Shambhavi Mudra would also deserve to be listed under samadhi mudras, but it is so important as a pratyahara mudra I have included it in this earlier category. Dhyana Mudra could have deserved a separate category of meditation mudras, but because this mudra is something of an anticlimax and has been treated like an orphan by shastra, I have refrained from this step and included it in this present section. Please also note that the English term meditation is ambiguous. It is sometimes used to translate the Sanskrit dhyana, but in yoga, it is the combined process of pratyahara, dharana and dhyana (yogic limbs five through seven).
4. Dharana Mudras
This is by far the most important section of mudras. They are all mudras designed to raise Kundalini. In his 1905 seminal textbook The Serpent Power, Sir John Woodroffe states that mudras are keys for opening the door to Kundalini. The connection between the term dharana (the 6th limb of yoga, often translated as concentration) and Kundalini is: With Kundalini raised, success in dharana is guaranteed. With Kundalini dormant, success in dharana is hard to come by. The mudras in this section are Maha-, Maha Bandha-, Mahav Vedha-, Ashvini-, Vajroli-, Pashini-, and Shakti Chalana Mudras. These mudras represent the main focus of the Hatha Yoga Pradipika, i.e. raising Kundalini. Authorities who believed this group of mudras to be the quintessential one necessarily concluded that mudras should be practised after pranayama.
5. Samadhi Mudras
These are mudras designed to trigger samadhi (revelatory ecstasy, the 8th limb of yoga). They cannot cause samadhi alone by themselves but only trigger it in a mind that already gravitates towards samadhi. Such gravitation is brought about through the long-term practice of asana, pranayama and yogic meditation. This category of mudras includes Bhramari-, Shanmukhi-, Jyoti-, and Khechari Mudras. As earlier stated, Shambhavi Mudra could have been included in this category, too, but its presence in the pratyahara category is too important and I didn’t want to list mudras twice.
HOW TO PRACTICE MUDRAS
Sir John Woodroffe in The Serpent Power explains that not all mudras need to be exercised by each person, but only as many as required in that particular case . With the order of categories created in the previous section, we can now easily analyse to which category Woodroffe’s statement applies. It applies to the categories 1 asana mudras, 4 dharana mudras, and 5 samadhi mudras. Of these three groups, we would select and add on only as many mudras as we need to achieve our respective goal. We would not learn them simultaneously but would focus on each one typically for 14 to 28 days before adding on the next . If we learn too many of the mudras in these groups simultaneously, we will create confusion. A typical example would be Maha Mudra, Maha Bandha Mudra and Maha Vedha Mudra. During the learning period, we would focus on each mudra individually and only eventually, once integrated, would we execute them all in sequence. Similarly is the situation with the asana mudras.
Different to that are the mudras in the classes 2 pranayama, and 3 pratyahara. Of these, most are practiced simultaneously as ancillaries to pranayama and meditation (the term meditation here again used in a general way for the compound of pratyahara, dharana and dhyana). This means these mudras are to be integrated as ancillaries into our pranayama and meditation practice without allocating extra timeslots to them. A case in point here is the group of the bandhas. The bandhas are all executed as a compound during our kumbhaka practice; application of all bandhas during kumbhaka is part of the definition of kumbhaka. Besides some initial experimental and tuition sessions, there will be no dedicated bandha time slot in our practice.

 Sage Vyasa argues in his Yoga Bhashya, commentary on the Yoga Sutra, that the mind settles on what the senses settle. Freedom of mind therefore is dependent on sensory freedom.
 From a birdeye view this could be seen as a tendentious statement as it reveals the present author to be more intersted in Kundalini-raising than in sthirata (fortitude).

 As taught by B.N.S. Iyengar, the 28-day period is refered to as a full mandala, because it reflects a complete moon cycle.
