 The reasons can be many, including not being disciplined enough to maintain the Khalsa code of conduct or due to personal reasons of them not believing they have enough commitment to become a full Khalsa Sikh.In the Sikh community these reasons are considered valid, as to renege upon them or break the Khalsa code of conduct, once becoming a baptized Sikh Khalsa, is considered one of the greatest sins in Sikhism, so it is better not to commit "(by not becoming a baptized Khalsa Sikh)" rather than to fall short later.They may have aspirations of receiving the rites of Khalsa baptism one day and maintaining the Five Ks, nevertheless, the ultimate ideal which they must realize in their lifetime is to become a baptized Sikh – a Khalsa.
