Bhishma loved the Pandava brothers and Sri Krishna with all of his heart. The straight truth as it is, is that Bhishma was a formidable fighter and an asset to Duryodhana. The hidden treasure is that he was weakened in his support for Duryodhana because of his deep love for the Pandavas. This sweet truth is also alluded to in Srila Prabhupada's commentary on text eleven of the first chapter of the Gita. Their lives are all about love, which resolves all contradictions.
Love harmonizes all things as nothing else can.
The lives of Srila Prabhupada and Srila Sridhara Maharaja and their relationship with one another are something from which we can learn about the spirit of love. To date, there has been considerable debate about the nature of their relationship. Thus, it is not understood by all, and certainly not without looking underneath the surface. If the beloved is arguing with her lover, we would be wrong to conclude that the two are not in love. Sri Radha speaks badly of Govindadeva, yet the real devotees of the two know the truth and depth of their love for one another.
