I am not saying not to be Spiritually discerning, for that is important. I am saying the glass of water is half empty or half full. If you look for imperfections you will find them. If you look for perfection you will find that as well. When your wife or partner does something wrong, instead of criticizing her, kiss her.
Love is a much better teacher than judgement and attack.
When your wife doesn't want to have sex, do not pout, or be angry, but look at this as a good Spiritual lesson in self mastery and nonattachment. Do not let too much time go by without making love, for this type of bonding is very important to a romantic relationship. Ask your wife what she likes and what satisfies her not just what you think does. Communicate freely about sexual matters and be willing to experiment and try new things without becoming over-identified with just physical sex. My Spiritual Brothers, be not afraid to let out your full passion on an emotional level and your sexual desire, but channel it through your heart so it is not just physical sex, for that is empty and will leave you empty feeling.
