From The Sutra of Contemplation of the Dharma Practice of Universal Sage Bodhisattva (Reeves, p420), something I want to set aside for future reference:

Having recited these verses, the Buddha said to Ananda: “Repent now of the six sense faculties, embrace the teaching of meditation on Universal Sage Bodhisattva, and explain it clearly everywhere for all the heavenly beings and people in all directions. After the extinction of the Buddha, if the disciples receive and embrace, read and recite, and explain the sutras of the Great Vehicle, the Expansive Teaching, in a quiet place, such as a graveyard or under the trees of a monastery, they should read and recite the sutras of the Expansive Teaching and should think about the meaning of the Great Vehicle. As a result of the strong power of reflecting. They will be able to see my body, the Stupa of Abundant Treasures Buddha, the countless buddhas embodied in all directions, Universal Sage Bodhisattva, Manjushri Bodhisattva, Medicine King Bodhisattva, and Medicine Lord Bodhisattva. As a result of revering the Dharma, these buddhas and bodhisattvas, living in the sky with wonderful flowers, will praise and revere those who practice and embrace the Dharma. And as a result just of their reciting the sutras of the Great Vehicle, the Expansive Teaching, the buddhas and bodhisattvas will make offerings day and night to those who embrace the Dharma. …

“After the extinction of the Buddha, if his disciples faithfully follow the Buddha’s words and practice repentance, it should be known that they are doing the work of Universal Sage. Those who do the work of Universal Sage neither see evil characteristics nor experience retribution from evil actions. If there are living beings who show respect to the buddhas in all ten directions six times night and day, recite the Great Vehicle sutras, and think about the profound first principle of the teaching of emptiness, in the time it takes to snap one’s fingers they will rid themselves of the sins of life and death committed during hundreds of myriads of thousands of billions of eons. Anyone doing this work is truly a child of the Buddha, born from the buddhas. The buddhas in all directions and the bodhisattvas will become their teachers. Such people will be said to be perfect in bodhisattva precepts. Without going through a special ceremony, they will become accomplished naturally, and be worthy of receiving offerings from all human and heavenly beings.”

Accomplished naturally without going through a special ceremony.
