Today we honor the Appearance of Lord Vamandeva, who, as some of you know, appeared as the fifteenth incarnation of Krsna. Lord Vāmanadeva assumed the form of a dwarf-brāhmaṇa [Vāmana] and visited the arena of sacrifice arranged by Mahārāja Bali. The following is a brief summary from Srila Prabhupada’s Srimad Bhagavatam, 8th Canto, Chapter 18.
Today also marks the Appearance of Srila Jiva Goswami, and there is a brief instruction given by him on understanding God at bottom of post.
Lord Vāmanadeva appeared in this world from the womb of Aditi completely equipped with conchshell, disc, club and lotus. His bodily hue was blackish, and He was dressed in yellow garments. Lord Viṣṇu appeared at an auspicious moment on Śravaṇa-dvādaśī when the Abhijit star had arisen. At that time, in all the three worlds (including the higher planetary system, outer space and this earth), all the demigods, the cows, the brāhmaṇas and even the seasons were happy because of God’s appearance. Therefore this auspicious day is called Vijayā.
