While Remembering Shri Radha Krishna and meditating on Their Divine form, you have to chant Their name, virtues and leelas with tears of love and longing with a deep desire to receive Their Divine Vision and Divine love. During devotion, loving meditation on Their form is of utmost important. As per your own liking, you may take the help of a Deity or a picture of Radha Krishna to form the image in your mind. But you must imbue Divine feelings in that because the body of Radha Krishna is always Divine and Blissful.
You can choose any form of Krishna or Radha from a newly born baby up to sixteen years of age and mentally decorate that form according to your own desire and choice. Along with the meditation on Their form, you should also remember Their loving leelas and virtues, such as: They are the true friend of every humble soul and a true companion of every fallen soul.
Keep this in mind that all the names, virtues, leelas, abodes and the Rasik Saints of Radha Krishna are one. You should always think that your Divine Beloved Radha Krishna and beloved spiritual master are always with you and are protecting you. Never ever think that you are alone.
While doing worldly duties chant “Radhey Shyam” or “Radhey Radhey” name with each breath. In this way, ‘Only They are my everything,’ this feeling has to be strengthened in the mind.
