Emptiness (ultimate truth, reality) and phenomena (relative truth) have never been contradictory to one another. As mentioned previously, some people mistakenly think that emptiness of the ultimate truth and the phenomena of the relative truth are contradictory after reading the Diamond Sutra and the Heart Sutra. They think that if emptiness is true, there can be no samsara; if samsara exists, it cannot be emptiness. But this is just their personal view. In fact, the two truths do not contradict each other at all. 

Take the earlier example of a piece of fabric. The observation can be made in reverse order from emptiness to the aggregation of quarks, atoms, molecules, etc. and finally wool. Wool can be knitted into yarn, yarn to fabric, and fabric made to clothes. Whether or not to take apart or put together the constituent elements the essence of fabric is actually the same. When put together, the existence of fabric is the relative truth. When take apart, the final non-existence of fabric is of the ultimate truth. The essence of fabric has never been separated from the ultimate truth, but in the relative truth, fabric exists and can be made into clothes. The two are not contradictory. Hence, it was said before that all matter can be defined by the ultimate truth and relative truth.
