How is air the enemy of the earth element?
Wind erodes rock. Balanced rocks, such as those seen at Jabalpur, got their rounded shape because wind kept striking them and wearing their particles away, so air destroys earth.

Can we create the mantras of the vastu devtas ourselves?
Yes. Use the name as Om Shri [devta name] Namah, or the beej syllable of the devta element between Om and Namah, since every devta is made of the five elements. These short mantras are easy for clients and no less effective than the long ones in Samarangan Sutradhar and Vishwakarma Prakash; offering bhog samagri uses a separate mantra.
