Early in my studies of Ayurveda, i became obsessed with Agni Mahabhuta(Fire element) and its mysteries and presence in the digestive tract of the body. Now, moving deeper into my practice, i am shifting my attention to Akasha Mahabhuta (Ether element) and realizing how integral the role of space / ether actually can be. Especially, with these dreaded Khavaigunya: either congenital, traumatic, or psychoemotional vulnerabilities in the physical tissues. Khavaigunya is a disposition towards a particular pathological process. It now seems imperative to study Akasha/Ether and how it may ultimately be the key to understanding plasma and blood (Rasa Dhatu) and certainly tissue formation in general.
तस्य आकाशात्मकं शब्दः श्रोत्रं लाघवं सौक्ष्म्यं विवेकश्च।(च.शा.४/१२)
Tasya aakaashaatmakam shabdaha shrotram laaghavam soukshmyam vivekaha cha (Ref – Charaka Shaareera 4/12)
Here what i find interesting is -Vivekaha- or the quality of Akasha that delineates boundaries between organs and vessels/sira. Here, we could argue that Akasha’s qualities directly impact the Srotamsi. or simply stated: Akasha = Srotamsi. Not to mention all hollow organs, those things that have an entry and exit have attributes of Akasha. This is the key element during unfolding a successful pregnancy during the symphonic formation of Deha, the gift of the body which is mostly empty space.
also-shabdaha-sound…the special quality of Akasha that allows us to ‘hear’ space but not perceive it directly. Ergo the utility of Auscultation in clinical examination for the ‘megolies’ or enlargement or hardening/constricture of organs. Similarly we can notice the increase/decrease of Rasa in said organs through listening to breathing patterns and heart rythms (ie, pleural effusion and avoid subsequent pneumothorax). Blood pressure can be a good indication of obstruction and qualities of space, too
कुपितानां हि दोषाणां शरीरे परिधावनम्।
यत्र सङ्गः ख वैगुण्यात् व्याधिः तत्र उपजायते॥ (सु.सू.२४/१०)
Kupitaanaam hi doshaanaam shareere paridhaavanam
Yatra sangaha kha vaigunyaat vyaadhihi tatra upajaayate (Ref – Sushruta Sutra 24/10)
Here kha is space and vaigunya is deformity of that space. That is where the circulating doshas will come to hide/rest/cause havoc. I also notice how Panchakarma therapies are but restoring emptiness to the body and thereby tonifying the Vata-stricken channels. Vata= Akasha + Vayu. Either some channels are constricted or some are enlarged/engorged. This is how obstructions form and Sroto Dushti occurs, by the qualities of space.
How would Akasha’s qualities affect Rasa Dhatu? Well, i think Rasa is very Kapha in nature so If there is excessive accumulation of phlegm/lymph/edema/mucous/and other exudates (morbid Kapha), it will be considered Prithiv/Jala imbalance with secondary Akasha imbalance as the channels become blocked causing further or tridoshic vitiation. Example: Sinus cavity filling with mucous/kapha causing pressure, pain, swelling. The space necessary and fundamental for the functioning of Pranavaha srotas is compromised allowing the arena for Rasa Dushti and beyond.
