Favourite Mahayana inspirational texts/treaties

I would like to ask the community here what are your favourite treaties or texts in Mahayana tradition that did personally make great impact on your practice in the way that it cut through illusion or allowed you to grow by breakthrough in understanding etc. It might have sentimental value of sorts. It might be a bullet point list with the title and description what it is and why it had such impact on your practice. Examples of such works could be Dogen - “Shobogenzo” or Shantideva - “Way of Bodhisattva”. It might be written from perspective of Vajrayanists but not about tantric practise per we.
