If from the beginning of life one is taught the Vaiṣṇava philosophy of duality or variety, the monistic philosophy will not bother him very much. In reality, everything is an emanation from the supreme source (janmādy asya yataḥ). The original energy is exhibited in varieties, exactly as the sunshine, the original energy emanating from the sun, exhibits itself in variety as light and heat. One cannot say that light is heat or that heat is light, yet one cannot separate one from the other. Therefore Lord Caitanya Mahāprabhu’s philosophy is acintya-bhedābheda, inconceivable nonseparation and distinction. Although there is an affinity between the two physical manifestations light and heat, there is also a difference between them. Similarly, although the whole cosmic manifestation is the Lord’s energy, the energy is nevertheless exhibited in varieties of manifestations.
