bhumir apo ’nalo vayuh
kham mano buddhir eva ca
ahankara itiyam me
bhinna prakritir astadha
"Earth, water, fire, air, ether, mind, intelligence and false ego—all together these eight constitute My separated material energies."
Here prakruti means the Moolprakruti. From it Mahaan was formed and from Mahaan, Ahankaram was made. Ahankaram brances into Saatvika, Raajasa and Taamasa ahankarams. Saatvika ahnkaram, gives rise to Five Gyanendriya, Five Karmendriya and Mind. Gyanendriya are the organs by which knowledge is acquired. These are eyes, ears, nose, tongue and skin which respectively understand light, sound, scent, taste and touch. By these one understands an object and so they are called Gyanendriya. Karmendriyas are the organs required to perform action. These are mouth - to speak or eat, hands - to hold or take, legs - to move, Payu and Upastham [organs for excretion (and reproductivity)]. Mind is the leader of these ten organs and so all together Saatvika ahankaram branches into 11 organs.
Taamasa ahankaram gives rise to Five great elements [Pancha Bhootha] and Five feelings [thanmathras]. Pancha Bhoothas are earth, water, fire, wind and space [prithvi, apu, tejas, vayu and akash]. Associated with these are five senses. They are sound [shabda], sight [roopa], scent [gandha], taste [rasa] and touch[ sparsa]. Thus ten entities emanate from Taamasa ahankaram. In all we have 24 entities : 5 [gyanendriya]+ 5 [karmendriya] + 5 [elements] + 5 [senses] + 1 [mind] + 1 [ahankaram] + 1 [mahaan] +1 [Moolaprakruti] = 24. All these are Achits. We should note the intimately connectivity of some of these.
- Eyes [gyanendriya]--> Sight [thanmatra]--> Fire [pancha bhhotha]
- Ears--> sound --> space
- Nose --> scent --> earth.
- Tongue-->taste --> water.
- Skin --> touch --> air.
