1. 68

    वहेर्विषस्य मध्ये तु चित्तं सुखमयं क्षिपेत् । केवलं वायुपूर्ण वा स्मरानन्देन युज्यते ॥ ६८ ॥

    One should throw the blissful mind into the fire (manipura chakra) in the middle of that fibre-like lotus stalk (sushumna) or into that which is only full of air (anahata chakra). Then one is united with the remembrance of bliss.
