वयो बुद्ध्यर्थवाग्वेष श्रुताभिजनकर्मणां ।
आचरेत्सदृशीं वृत्तिं अजिह्मामशठां तथा ॥
One must keep himself busy with occupation that suits his age, intelligence, wealth, language (speaking ability), dressing sense, education, lineage (family born into) and skill. At any cost one must not cheat. One must not walk down the path of dishonesty.
