Yoga is not a competition in which you have to prove your ability; it is meant to develop sensitivity and consideration toward our bodies and mind. Geeta Iyengar writes: "It is only a question of how we adapt the practice so that it brings a proper balance and becomes suitable as far as the physical body and mental capacity is concerned. So we are supposed to understand this basic fact regarding the adoption of adjustments in the practice. " The first rule is that you should avoid inverted asanas. Geeta explains why: "You avoid Śīrsāsana and Sarvāngāsana or any inversions during menstruation because the inversions are a hurdle to the menstruation‘s flow. The inversions arrest the flow. When you are standing on your head or on your shoulders you retain that which is only fit to be thrown out." In addition, do not practice abdominal asanas (like Paripurna Navasana) or twisting that harden or squeeze the abdomen (like Marichyasana III). Instead, practice supine poses like Supta Svastikāsana and Supta Baddha Konāsana; sitting asanas like Vīrāsana and Baddha Konāsana and forward extensions, like Jānu Śīrsāsana, Paśchimottānāsana, Upavistha Konāsana.
