A follower of Guruji's path would not date, because lust, KAAM, is wrong, and dating would mean seeing somebody different to a brother/sister/mother/father/relative as Sikhi teaches, or even just respecting them as a friend which is possible in today's world. God is our true love, and all other love is false and simply something we may want or like to feel we have. Waheguru has blessed us with Gurbani, and many people who have been blessed with Amrit wil know that in an amrit sanchaar it is said that one of the cardinal sins is any intimate relationship outside of marriage. to put it clearly, intimacy involves kissing or ANY sexual behaviour which is wrong. This means before or after marriage, there should be nothing.
Dating is seeing someone with wrong intentions, you don't know who u are going to marry so this is not what Guruji's Grihasti jeevan is. That refers to marriage.
If you have no wrong intentions, then c tht person of the other sex as your brother/sister or even a friend. Respect yourself and respect others. God has given us a wonderful gift of purity, why taint it? And, somebody who is clean and not dated or had any relationship is much more desirable than somebody who has been with anyone.
Today's society is just an excuse to mess up, but it is possible not to by begging God for love and faith, and Gursikhi jeevan. Personally i know i was blessed to never date or do anything intimate even before the wonderful gift of amrit, because God is our saviour, God does everything to protect Their children. But why can't we do anything for God?
Nobody is perfect, but Ardaas and trying to do the righteous thing will take you a long way. Do not be fooled by society that dating or any relationships before marriage, not just sexual, are ok..this isn't the case.
Guru Tegh Bahadur Ji told Guru Gobind Singh Ji Maharaj that it is a sin to even dream of another woman other than your wife..and sikhism teaches equality so girls it applies too! Since we dont know who we r going to marry, and only Waheguru can account for each breath, we shudnt hav thoughts of anybody.
Even engagement is not marriage and so try not to see the person with lustful thoughts or in any way other than brother/sister/respectful friend. Until you have united with God in Lawan, and taken Guru Granth Sahib Ji Maharaj's blessings, you are not married. God is your One, and the spouse you are given here is your support for your journey, nothing lustful.
I know there may be many mistakes in this entry, yet Waheguru and Gurbani hold deep answers to this question which prove that Waheguru is all and grihasti is married life..
please lets all take time to try to understand this, and fight kaam/kaljug
Waheguru Ji Ka Khalsa Waheguru Ji Ki Fateh...
Khalsa..Pure... think about it
