The first one is called Devotion Beyond Concepts:
The second is Cultivating Devotion and Sometimes Saying No:Kyabjé Tulku Urgyen Rinpoche used to explain that devotion and love were both the rising of uncontrived love. When the object of that love is beings who are less fortunate (i.e. lost in samsara), then we call it compassion. When the object of uncontrived love is beings who are more fortunate than we are (i.e. the buddhas, bodhisattvas and great teachers), we call it devotion. It is through the transformative power of intense uncontrived love, that the naked empty essence of our mind will be directly revealed.
And the third one is called Infallibly Inseparable:The practice of cultivating devotion is challenging and the process can be messy. We need to be gentle with ourselves. The point isn’t to have a set of rules about when to say yes or no, but to figure out how to be as authentic, vulnerable, and responsive as we are capable of being in any given moment. We don’t have to make ourselves go where we aren’t ready to go. It’s just like although Buddha fed himself to a lioness in a previous life it doesn’t mean that we should. We don’t have to force ourselves to live up to someone else’s ideals about devotion; devotion is about not being deceitful or hiding, and flexibly trusting a process rather than living up to a result we may not have realized personally yet.
Our dharmakaya nature is stainless, faultless or infallible. We can even get a glimpse of this in ordinary experience. The awareness that is the basis of mind, the knower of all experience is never harmed. When we are dull and sleepy or when we are sick or when we are elated, the quality of knowing is exactly the same. What is known changes, but the quality of knowing, stays the same. When we are dull, we know it, when we are sick, we know it. The knowing isn’t impeded by what appears in the mind. The knowing is unstained, unharmed by what is known; it is infallible. This example is to give you a sense of infallibility, but it’s just a glimpse.
