Hi dsiluvu
In Lama Chopa its says:
"I seek your blessings to make this freedom and endowment extremely meaningful, by immediately applying meditation to whatever I meet..."
In Geshe Chekawa's 7 Point Mind Training it says:
"All Dharma is condensed into one purpose." (Subduing our uncontrolled mind = training the mind)
In many places we see the Masters saying that Dharma is about training the mind; that things are a projection of mind; that our experience depends on our view and so forth.
Making a distinction between serving our children and practicing Dharma 100% is a mistaken view. Although we may not be able to do extensive isolated solitary retreat until the children are older, if we maintain powerful mindfulness of Dharma, of our intentions and views in relation to what is appearing, and we apply ourselves correctly in formal meditation and sadhana, we make quick progress.
'Sadhana' means method of attainment. Traditionally, this word meant the complete transformation of every aspect of our life 24/7 into our sadhana. Nowadays people just tend to think of the prayer booklets.
Children, as an object of our consciousness, contribute to the quick path in many many ways. Because of them, we can develop various types of love, compassion, exchanging self with others, bodhichitta. We are able to train deeply in patience, in generosity, in skillful means, in moral discipline, in effort, and so forth. We are reminded of our own samsara, so we can enhance renunciation. We are reminded of impermanence, so our grasping at permanence and this life reduces. The fact is, to become a Buddha, we have to gain control of our mind and perfect our good qualities, and it is in dependence upon objects of consciousness that we are able to train. How was Atisha's angry and abusive cook contributing to Atisha's quick path? Atisha said 'I need him, because I am able to complete the perfection of patience through his kindness.'
If we practice in this way throughout the day and night, regardless of what we are doing, who we are with, or where we are at, we will progress quickly. If we engage in virtue and training the mind between formal meditation sessions, when we sit down to concentrate in formal meditation, it will be powerful because we have been engaged in preliminaries all day. For such a practitioner, making strong distinctions between what is spiritual practice and what is not, and between the meditation session and meditation break is foolish. For them, children enhance every aspect of their training in Lamrim, Lojong, and Vajrayana Mahamudra. An entire book could be written about this relationship between children and the quick path.
Every moment is an opportunity in every situation is an opportunity for powerful spiritual progress. As long as we think otherwise; as long as we think some things are not of spiritual benefit, we will be slowed down by our own useless imputation of reality. The choice is ours.
If everything is viewed as the Guru, we receive the blessings of the Guru. If everything is viewed as the Guru teaching us the path of abandonment and practice, giving us the opportunity to generate the path in our own consciousness, then everything we experience will become the quick path of realization. That is a fact. Everything we experience is the kindness of the Guru!
If the lineage Gurus are any indication of what happens by holding such a view, then we can be sure if we do the same, we will achieve the same results. The law of karma is infallible.
