There are many ways of practicing to gain power in his memory but mainly used system all over the Aryavarta is prana and dhatu transmutation .
Once completely mastering these two produces energy ojas and tejas.
After one mastering prana they also cleaned the sushumna nadi so they can practice the higher system called Chakra system (7 chakras)…but this system only for later period .
Now let’s talk about prana system
The Prana System is the cultivation of the Universal Life Force within the human body through breathing.
Prana travels through a network of 72,000 subtle energy channels called Nadis.
To master Prana, a practitioner must systematically control, balance, and hyper-compress the Pancha Pranas (the 5 primary winds or currents moving through the body).
And also mastering the pancha pranas gives the practitioner 5 different kinds of powers
Prana Vayu (The Inward Current): Centered in the chest and head, this wind rules over sensory intake.
Cultivators who master it achieve Hyper-Perception.
Their senses sharpen to a supernatural degree, they can hear a leaf fall miles away, see in pitch darkness, and enter Kevala Kumbhaka—completely halting their physical breathing for hours on end.
Apana Vayu (The Downward Current): Rooted in the pelvic floor, this wind normally governs waste, reproduction, and the body’s downward gravitational pull.
Reversing this current is the key to Absolute Immunity.
By forcing Apana upward into the internal fire, a cultivator halts biological aging, neutralizes toxins, and severs the shackles of gravity to achieve true flight.
Samana Vayu (The Centering Current): Residing in the navel, this is the equalizer.
Turning this current inward ignites the Psychic Furnace.
Cultivators can stand naked in sub-zero arctic blizzards, metabolize deadly poisons like water, and convert ordinary food into pure energy
Udana Vayu (The Upward Expression): Flowing through the throat and spine, this current controls weightlessness and Astral Projection.
A master of Udana can leap across canyons and walk across water without leaving a ripple.
In combat, they can project an “Astral Echo”—a solid phantom a few feet away—forcing an enemy to strike a ghost while the real body delivers a fatal blind-spot blow.
Vyana Vayu (The Pervasive Current): Coiled throughout every nerve, muscle, and fiber, Vyana coordinates total circulation.
Mastering it unlocks the legendary 10,000-Elephant Shield—the very technique Bhima and Duryodhana used to survive world-shattering blows.
By flash-compressing their entire Prana reserve into a single cell within a millisecond, the cultivator’s skin becomes utterly impenetrable.
In human body all the 72000 nadi are blocked ,the prana is used to open the blocked nadi.
Even without fully mastering the pancha pranas one can still unlock the 72000 nadi but in slow speed
Once the all the 72000 nadi are unlocked they can start dhatu transmutation .
By unlocking all 72000 nadi they gain extraordinary physical strength and clear sight , perfect digestion, The physical body feels completely weightless, free of all stiffness, aches, and pain.
he can fell that he already unlocked 70000 nadi in his body and also taken full control of pancha pranas ,
so by unlocking the 2000 nadi he can finish the first stage prana ,next he can train for dhatu transmutation
Karna moved away from the balcony ,He pulled a piece of parchment toward him, began to chart the geopolitical landscape of Aryavarta.
he mapped out the factions, their borders, and the exact military statistics of the major kingdoms.
He drew a grid on the parchment, detailing nineteen powerful kingdoms across Aryavarta, their geographical neighbors, and their standing army counts measured in Akshauhinis (one Akshauhini: 21,870 chariots; 21,870 elephants; 65,610 horses; 109,350 infantry).
Hastinapur (Dhritarashtra / Bhishma): 11 Akshauhinis.
Panchala (Drupada): 5 Akshauhinis.
Hostile border with Hastinapur
Magadha (Jarasandha): 8 Akshauhinis.
The terror of the east, bordering anga
Anga (Karna): 1 Akshauhini.
Borders Magadha to the west, Vanga to the south, Pundra to the east.
Dwarka / Yadavas (Krishna / Balarama): 6 Akshauhini (Narayani Sena).
Karna circled Anga and Magadha.
He knew Jarasandha would remain the immediate danger, while the Kuru-Pandava conflict would escalate into a continent-wide war.
He also start to think what happens next .
the Crown Prince debate, Drona’s demand for Guru Dakshina
The first will happen would be selection of Crown Prince .
Dhritarashtra wants to name Duryodhana as king but Bhishma and Mahamantri Vidura against it and also want to choose Yudhishthira as a king but before it ends ,Drona will stop everyone in the name of Guru Dakshina..he says without giving Guru Dakshina nobody can become king….
But Drona will ask Guru Dakshina as war with panchala …
even though Dhritarashtra doesn’t want fight this war, in the end because of duryodhana and Arjuna.
He will accept the war against Panchala, at the same time Bhishma and vidura uses the battle to determine the who will be next King ..
Duryodhana will think of using me in the war.
he will become next king but Drona will never accept it .
When dorna not allow me to participate in the war,it will be the perfect peacefull time for me so I will take the time to develop the anga and practice the prana system to mastery and start to practice dhatu transmutation ..
and I also start to prepare for the future battles with Magadha…
If I didn’t become a king of anga ,I don’t care about ruling or conquering other kingdom.
But I already become king of anga why can’t I enjoy being a king for some time.
I also need to think about learning new knowledge some where because parasuram cursed me ,I cannot learn new knowledge from him ..unlike me Arjuna will learn new knowledge from Drona(brahmashira) and in Indra Loka (many powerful divine astras), also get astra from Mahadev (Pasupatastra) …
I only learned 21 divine astra including bharmastra, but in future Arjuna learns more than 30 astras ,also some astra can kill me immediately but they cannot used because of restrictions like cannot used unless he pushed to dead end or not used against mortal, only used against the devas and asura ..
In ramayana I read vishwamitra possessed more than 50 astras, he given this knowledge to rama ….
So I didn’t even have the half of the astra he possessed.
So I need to find a ways to learn astra knowledge to increase my reserves ….
