However, O best of the Bharata Dynasty, those sacrifices that are performed out of pride and with selfish intent should be considered to be in the mode of passion.
Bhagavad Gita - Chapter 17 - Shraddha Traya Vibhaga Yoga - The Yoga Explaining Three Types of Faith
That sacrifice which disregards Vedic rules, where no food is given in charity, which is without the chanting of proper mantras and without charity to the brahmanas – such a sacrifice is faithless and in the mode of ignorance.
Proper physical austerity consists of worshipping the Supreme, the brahmanas, the spiritual master and the wise, as well as purity, sincerity, celibacy and nonviolence.
Truthful speech that does not disturb others, which is pleasing and beneficial as well as the recitation of the Vedas – this is known as verbal austerity.
Mental austerity is said to be peace of mind, gentleness, silence, self-control and purity of heart.
When these three types of austerity are taken up with strong faith by one who is strict and who is without selfish motivation, they are said to be in the mode of goodness.
Austerities that are performed with pride in order to achieve prestige, name and fame are said to be in the mode of passion. The results of such austerities are unstable and temporary.
Austerities performed out of foolishness that inflict pain on oneself and others, are said to be in the mode of ignorance.
Charity that is given without any expectation of reward, at a proper place, at an auspicious time, to a qualified recipient with the mentality that it should be given, is in the mode of goodness.
However, charity that is given reluctantly, with the expectation of return and with a selfish desire for results, is in the mode of passion.
