The path of Secret Mantra is one of both great profit and danger. Therefore, anyone who practises these texts should receive the empowerments, reading transmissions, and instructions from an authentic spiritual teacher, doing so in the correct manner. Once the essential practice has been perfected, it is certain that both the dharmakaya and rupakaya will be attained. For this reason, I request that these points be kept in mind.
