DANCING
In Sikhism, there is no prohibition for making merry and dancing. Dancing in public and/or with someone who is not one’s spouse is not in accordance with Sikh ethics because such dancing is likely to lead to illicit relationships and immoral life.
In Sikhism, dancing and making merry is “a (petty) pleasure of mind” as the real pleasure is living truthful life in the (‘sacred’) fear (of God; it is, in fact, respectful love for God). (Guru Granth Sahib, p. 465).
