Mbh 12.266.2h

If it is the abandonment of a project already begun, one should abandon it after a long while. A friendship that is formed after a long examination lasts for a long time. In giving way to wrath, to haughtiness, to pride, to disputes, to sinful acts, and in accomplishing all disagreeable tasks he that delays long deserves applause. When the offence is not clearly proved against a relative, a friend, a servant, or a wife, he that reflects long before inflicting the punishment is applauded.' Thus, O Bharata, was Gautama pleased with his son, O thou of Kuru's race, for that act of delay on the latter's part in doing the former's bidding. In all acts a man should, in this way, reflect for a long time and then settle what he should do. By conducting himself in this way one is sure to avoid grief for a long time. That man who never nurses his wrath for a long while, who reflects for a long time before setting himself to the performance of any act, never does any act which brings repentance. One should wait for a long while upon those that are aged, and sitting near them show them reverence. One should attend to one's duties for a long time and be engaged for a long while in ascertaining them. Waiting for a long time upon those that are learned, are reverentially serving for a long time those that are good in behaviour, and keeping one's soul for a long while under proper restraint, one succeeds in enjoying the respect of the world for a long time. One engaged in instructing others on the subject of religion and duty, should, when asked by another for information on those subjects, take a long time to reflect before giving an answer. He may then avoid indulging in repentance (for returning an incorrect answer whose practical consequences may lead to sin).--As regards Gautama of austere penances, that Rishi, having adored the deities for a long while in that retreat of his, at last ascended to heaven with his son."'"
