We cannot know who is a sublime being.

Do not examine the faults of beings. Recognizing that they have been your mothers and thinking of their kindness, meditate on love and compassion. In particular, avoid looking for faults in those who have entered the gateway of the Dharma. Regard them as people in the same boat and reflect only on their good qualities, rejoicing at these and cultivating devotion. More especially, never look for defects in your teachers. Realizing that everything they do is full of excellent qualities, make an effort to train in devotion and pure vision.

A greater fault than stealing the possessions of all the beings in a billion worlds and destroying all the stupas there are is criticizing a single Bodhisattva. If one scorns and insults a Bodhisattva, whatever the circumstances, one will be reborn in the Screaming Hell with a body five hundred leagues in size, with five hundred heads, each with five hundred mouths, each containing five hundred tongues, and each tongue plowed by five hundred plows.

Take note of this passage from the Sublime Sutra of the Marks That Inspire the Development of Faith

In general, it is a boundless crime to criticize a sublime being.  In this respect, Bodhisattvas are particularly dangerous objects, and Secret Mantra Vehicle practitioners even more so. We cannot know who is a sublime being or whether someone is inwardly a genuine practitioner. It is said that only a fully enlightened Buddha can judge; no one else can do so. If we speak badly of anyone or criticize them, we are sweeping away our own qualities. It is in the nature of things that by finding faults in others, we ourselves are destroyed. Change your attitude, therefore, and examine only your own faults.

“For beginners, it is not the time to struggle with afflictive emotions, but time to run away from them.”

The Three Supreme Methods

Whatever practices we do, whether the common ones of taking refuge and making prostrations, the various trainings in bodhichitta, the methods for purifying the defilements of body and speech, or the uncommon practices of the Secret Mantra (the visualization and recitation of Vajrasattva, guru yoga, or meditation on the yidam deity), all that we do—and this is very important—should be accompanied by the three “supreme methods.”

The first of these methods is the attitude of bodhichitta. All beings possess the
tathagatagarbha, the seed of buddhahood, but this is obscured and veiled. As a result, they wander in samsara. The first method is therefore to be determined to liberate them from this ocean of suffering.

The second supreme method is to have a mind free from conceptualization, which means to practice without distraction. Even if we make only a single prostration, we should not just go through the motions mechanically, with our thoughts and words elsewhere. On the contrary, we should practice with a concentrated mind, and never be carried away by distraction.

The third supreme method is to conclude with dedication. Whatever merit has been generated must be dedicated for the sake of beings, who are as many as the sky is vast. In fact, if we forget to round off our practice with the excellent attitude of bodhichitta, dedicating the merit to others, this merit could be destroyed in a moment of strong anger or defilement.

For this reason, all positive actions should immediately be followed by an act of dedication for the welfare of all beings. The benefits of this supreme method are immense; dedication renders merit inexhaustible and causes it to increase constantly.

This is what your Dharma practice should be like.

We have all entered the Vajrayana. We have received profound empowerments and instructions of the Secret Mantra. This is said to be very beneficial but it is also very dangerous. Even if we are unable to bring our practice to accomplishment, if we keep our samaya unbroken, it is said that liberation will be achieved in seven lifetimes. After crossing the threshold of the Secret Mantra, however, if we ruin our samaya by displeasing the Lama, causing havoc among our fellow Dharma practitioners and so on, the only possible destiny for us is the vajra hell. The saying goes that practitioners of Secret Mantra either attain buddhahood or go to hell. There is no third alternative. It’s like a snake inside a cane: it must go either up or down. There’s no way out halfway! Think carefully about the benefits and hazards of samaya, and observe it purely and perfectly. To do this, it is crucial to keep a close watch on your mind, a practice in which all the essential points of the teachings are condensed. It is vital to examine and watch your mind. You have all received instructions through the kindness of your teachers. This is what your Dharma practice should be like.
