พื้นดินย่อมบริสุทธิ์ด้วยการขูดปรับให้เรียบ การทาดิน/ชโลมสิ่งชำระ และการกวาดทำความสะอาด อีกทั้งบริสุทธิ์ด้วยการที่โคพำนัก และยังถือว่าบริสุทธิ์ด้วยการพรมน้ำ

It prescribes bhūmi-śodhana—purifying the worship area—so the Linga-pūjā is performed in a sāttvika, consecrated space suitable for invoking Pati (Śiva) and removing ritual obstacles.
