The following is a teaching by His Holiness Penor Rinpoche
We are born in this Zambu-dweep world and have acquired the precious human rebirth due to the gathering of the compositional factors of the eight leisures and ten blessings. This is a most perfect and auspicious opportunity. That we are fortunate enough to receive the teaching of perfect Buddha dharma and also be able to meet so many qualified teachers is the result of the ripening of our positive merits from countless past lives.
But due to our attachment from time beginningless towards the repeated pattern of samsara, we have developed strong emotions towards this samsara. Therefore, it is common for sentient beings to find themselves emotionally drawn towards the attainment of worldly concern regardless of difficulty and hardships, which in turn generates all types of karmas in the process.
If we truly want to learn the teaching of Dharma, we must first find a qualified teacher. Buddhism has Mahayana and Vajrayana traditions, of which Vajrayana and especially the Great Perfection (Dzogpachenpo) is especially beneficent for the degenerated times like now. The actual practice to Dzogchen consists of preliminary and the main practices, that has visualizations, recital of mantras and the sadhanas.
In fact, we might all think we know about Dharma and might even want to practice these teachings, but because of our attachment to worldly distractions, we are not able to practice accordingly as instructed, as if we show no concern for the effect of karma, as though karma is not real and does not really exist, and thus as a result, succeed in continually creating more negative karma. Only at the end of our lives, when we come face to face with the imminent sufferings of death, do we start thinking that we should do something about it! But by that time, even if we come to realize that we have not studied the Dharma and neither have we applied ourselves properly according to the pith instructions of the teacher and hence the prospect of falling into the three lower realms is imminent; the time of seeking the Dharma and practicing has already passed, so now what do we do?
