It is not the light that is needed in this world but the warmth because we will die out of cold but not out of darkness.
The Supreme Personality of Godhead is the best friend and well-wisher.
Srimad Bhagavatam 8.9.27
Radharani is compassionate nature of Krishna.
This perfect stage of self-realization is attained not by artificial means, but under the lotus feet of the Lord, who is always transcendental.
Srimad Bhagavatam 1.3.33,
Sometimes river flows very strong, sometimes it flows very small, but it makes no difference to the ocean because it is satisfied in itself with its own quantity of water. Similarly, when our heart is cleansed with spirituality, we find pleasure and ecstasy with our own selves that is so sweet, so wonderful and so satisfying, that the so-called pleasures of this world no longer have any values, no appeal at all.
Everyone is hankering for happiness because by nature we are happy : anandamayo 'bhyasat (Vedanta-sutra 1.1.12). As spirit souls we are naturally happy, blissful.
