In the purport to Verse 29 in the seventh chapter of Madya-lila of the Caitanya Caritamrta, Srila Prabhupada writes, "There are many instances of devotional service rendered by pervious acaryas who did not care about social behavior when intensely absorbed in love for Krsna. Unfortunately, as long as we are within this material world, we must observe social customs to avoid criticism by the general populace. This is Sri Caitanya Mahaprabhu's desire." Some devotees are greatly upset by the fact that the Royal Society for the Prevention of Cruelty to Animals (RSPCA) "secretly" euthanized a cow at Bhaktivedanta Manor. The above quote may be a way to understand that God's law versus the laws of Manu is an issue that's not easily resolved. Lord Caitanya operated under Pathan law.
