One of the best and the easiest methods of creating a sense of family togetherness, is to hang a large family photo in the South-west corner in the living room. Every member of the family should be included in the picture, and to symbolize happiness, each one in the photograph should have a smiling countenance.
This is especially effective in the Indian joint family concept, where mother-in-law vs daughter-in-law tiffs are common.
Hang a photo of both together, and smiling, and in a loving happy pose, to enhance their relationship.
A married couple should hang a photograph of the two of them together in a happy loving pose, in the south-west corner of their bedroom to enhance their love and affection.
