This is Uvakkaayyan - The Loka of Unconditional love. It is traditionally used by Aaiyyanists to send love, positive energy, wellness and spiritual aid to someone they love. It is usually used by many Aaiyyanists to focus their love onto a group or an individual. In other words it is a collective act of many Aaiyyanists that is designed to empower and aid someone they deeply care about.
The Uvakkaayyan Loka is a space of Oneness and love and is a dimension that opens when we care for someone deeply. It is a dimension that takes our love and amplifies it and focuses it to the person we direct it to. It is a very powerful dimension that amplifies and strongly resonates pure love, such as the love between a parent and their children. If you have experienced this love you will know how powerful Uvakkaayyan can be. It is especially powerful when used by a group of Aaiyyanists to focus on one person or a family. It was first revealed by Murugan-Aaiyyan, and this is an Aardranal form of this Loka Yantra.
The best way to use this Loka (or become more attubed to it) is to draw it, meditate on it, chant the mantra of 'Uvak Kaayyan' and also focus on the person you wish to send your unconditional love to. Your Aaiyyanist power will infuse with the Loka (dimension), become amplified and be directed at the person you love.
