Other then giving Birth to Buddha she didn't really do anything of great Importance compared to Buddha's enlightenment and turning of the wheel of Dharma. Only Buddha experienced his mothers kindness where as all Buddhist practitioners experience Buddha's kindness through his setting the wheel in motion.
Abandoning Dharma is, in the final analysis, disparaging the Hinayana because of the Mahayana; favoring the Hinayana on account of the Mahayana; playing off sutra against tantra; playing off the four classes of the tantras against each other; favoring one of the Tibetan schools—the Sakya, Gelug, Kagyu, or Nyingma—and disparaging the rest; and so on. In other words, we abandon Dharma any time we favor our own tenets and disparage the rest.
