• Baddha Konasana refers particularly to first, the Muladhara Chakra, with the Perineum, thus location of the genital organs and the perineum. The Perineum works like a hammock, between pelvic floor muscles to the seat bones. These muscles give substantial support to the sex organs. Thus the first Chakra is brought with fundamental surviving in connection - with feelings, needs, fears and expectations, which concern the three fundamental topics of the life: Sex, birth and death (separating).
• Baddha Konasana also refers to the second chakra, Svadhisthana, is sexual, and can have a lot to do with past relationships. Sexual problems and discomfort in the lower back, hips, and reproductive organs can also signify that this chakra needs some kind attention
