If you catch one of her knees firmly in your hand and stand making love with her while her hands explore and caress your body, it is "Tripadam" (the Tripod). 

If she raises one leg and you catch hold of her little foot, caressing her breasts and telling her how much you love her, it is "Ekapada" (One Foot). Her foot pressed to your heart, your arms encircling and supporting her, lean back against the wall and enjoy the lovely girl: this is "Veshta" (the Encircling). 

She stands against the wall, lotus-hands on hips, long, lovely fingers reaching to her navel. Cup her foot in your palm and let your free hand caress your angel's limbs. Put your arm around her neck and enjoy her as she leans there at her ease. Vatsyayana (the author) and others who knew the art of love in its great days called this posture "Tala" (the Palm).
