Heart failure means
Bhagavad-gita As It Is Lectures
Mahāmāyā: Śrīla Prabhupāda, is Kṛṣṇa in our heart, in the heart of the body and in the heart of the spirit soul?
Mahāmāyā: In His two-handed form and in His four-handed form, is He in our heart?
Prabhupāda: In the heart you are also there. In the medical science the every energy is coming from the heart. Heart fails; then that means the spirit is not there. Heart fails means the spirit soul and the Supersoul goes away. That is heart fail.
Devotee (4): Prabhupāda, what does it mean to chant seriously?Prabhupāda: Without offense. You know there are ten kinds of offense? That's all right.
