When the patient lies on his left side, both the grahaņi and guda remain in normal position. Basti administered in this position gets absorbed properly and distributed easily. In this position, the sphincters remain relaxed. Therefore, the enema fluid enters into rectum easily without any obstruction and impregnates the grahaņi to produce the desired therapeutic effect.<ref>Chakrapanidutta, Commentator.  Charaka samhita, Siddhi Sthana, 3/24-25, edited by Vaidya Jadavaji Trikamji Acharya, 2nd edition, Chaukhamba Sanskrit Sansthan, Varanasi, 1990</ref>

Basti drug reaches first to the pakvāśaya and then to the grahaņī. Pakvāśaya is the site of purīshadharā kalā and grahaņī is the site of pittadharā kalā. So basti directly acts on Purīshadharā kalā and Pittadharā Kalā. Commentator Ďalhaņa has commented that Purīshadharā and asthidharā kalā are same and pittadharā kalā and majjādharā kalā are one and same.10 So from these evidences it is clear that basti has direct action on asthi and majjā dhātu. Majjā is present in the asthi. Also mastulunga is considered as mastaka majjā.11 Vāta nāďi are also made by majjā which is the seat of vāta dosha. So in this way, basti is useful in the disorders of central nervous system.

It is thought that an enema introduced would never ascend so high as the stomach. There is a referance from the Best and Taylor that “materials introduced by enema, in some instances pass through the walls into the ilium, such incompetence may permit the enema fluid to reach the duodenum.” Also the possibility of materials from even the lower bowel, reaching the mouth is strongly suggested by the fact that lycopodium sporce, introduced into the colon by enema, has been recovered some hours later from washing of the stomach.12
