Param Pujya Sri Sri Ravi Shankar explaining the esoteric meaning of Krishna Janmashtami.
Other submitted details:
When Krishna was born, the guards went asleep (senses turned inwards). However, Devaki (the body) could not sustain Krishna (the bliss), he had to be taken to Yashoda (the love, devotion). Otherwise Kamsa (the ego) might kill Krishna (once the ego arises, it perverts the pure bliss or love).
So in order to protect that Bliss or Infinity, the prana (Vasudeva) takes it across the river of love/devotion (Yamuna).
Infinity is born out of yoga and meditation (the union of body and prana/mind), but yoga alone cannot sustain it – what is needed to nourish it, to allow it to mature and blossom, is devotion (bhakti) and love.
I wish all a beautiful Krishna Janmashtami.. that Krishna may be born in your life, and fill your life with Love, Infinity and Bliss!
