Part 1a - Meditating in the style of being born from an egg

Second, within the practice of meditation, there are the stages of the empowerments that ripen the ground, and the stages of developing and completion that liberate the path. From the three sections of extensive explanation of the actions associated with these along with the associated samayas, now there is the brief explanation of the way of meditating in the developing stage:

There are four styles of practice that match with the four births.
To cleanse habitual patterns of being born from an egg,
At the time of preliminary practices
By going to refuge and arousing bodhicitta,
And briefly doing the practice of the developing stage,
After the offerings that invite the field of merit,

Also by meditation on the absence of self-nature,
Having first gathered together the two accumulations,
With a first meditation, performing the extensive stages
of the practices of development and completion,
Is like an egg from which a bird will first be hatched.
Perform the short and elaborate development and completion.

In this first stage of secret mantra, in however many samadhis of visualized deities we may meditate, habitual patterns of the four modes of birth are trained and harmonized. These are taught as four. The Net of Miracle says:

There are four modes of birth that are to be purified.
Therefore, visualization has four different stages.
These are the greatly complex and the complex,
And those without and completely without complexity.

This is explained as it was clearly presented by the great master Vimalamitra. Those who are born from an egg are as if twice-born. At the time of meditation on the samadhi of great complexity, first we go to refuge and arouse bodhicitta. We instantly visualize ourselves as the chief deity and consort. In the space in front, invite the mandala of deities. Make offerings and praises to that mandala, confess evil deeds, rejoice, urge the turning of the wheel of Dharma, supplicate for desirable qualities, and dedicate the merit. Then after saying “VAJRA MUH go to your own places,” meditating for a while in objectless meditation, gather the two accumulations of merit and wisdom. This is the brief meditation. After that, arising from emptiness and meditating extensively on the mandalas of the individual deities is the extensive meditation.
