Does
one need to abstain from sex in order to practise meditation?
For lay-people
there is no prohibition against sex, as long it is moral sex.
There is no reason why one cannot enjoy a happy sexual life while
also training oneself in meditation. It has been advised that
husband and wife should meditate together before going to bed
in order that any child that is subsequently conceived will be
born clever, high-minded and respectful towards the parents.
