NOTE. Why is all-around auspiciousness rare? Because pure devotees of the Supreme Personality of Godhead are fully engaged in all-auspicious activities and they are rare for they have understood that ultimately, pure devotional service unto the Supreme Lord is the only auspicious activity. This is explained by Prabhupāda thus:

Those who are following the path of auspiciousness can be divided into three sections, namely (1) the followers of scriptural rules and regulations who are enjoying material prosperity, (2) those who are trying to find ultimate liberation from material existence, and (3) those who are devotees in Kṛṣṇa consciousness. Those who are following the rules and regulations of the scriptures for material happiness may be further divided into two classes: those who are fruitive workers and those who desire no fruit for sense gratification. Those who are after fruitive results for sense gratification may be elevated to a higher standard of life—even to the higher planets—but still, because they are not free from material existence, they are not following the truly auspicious path. The only auspicious activities are those which lead one to liberation. Any activity which is not aimed at ultimate self-realization or liberation from the material bodily concept of life is not at all auspicious. Activity in Kṛṣṇa consciousness is the only auspicious activity, and anyone who voluntarily accepts all bodily discomforts for the sake of making progress on the path of Kṛṣṇa consciousness can be called a perfect transcendentalist under severe austerity.
