Please accept my humble obeisance. All glories to Srila Prabhupada
A Krishna-bhakta with awareness, devotion and self surrender, will continuously receive Bhagavan Sri Krishna's personal guidance . Once the Bhakta tunes Himself with Bhagavan, the scriptures are reborn.The Vedas and Upanishads are repeated.
Everything is Sri Krishan, there is nothing else but Bhagavan. This is the single message in the Upanishads, Vedas, Bhagavad Gita and Puranas. When we say that there are 108 Upanishads, we should understand that it is actually, 108 different ways of conveying the same message.
Happiness is within everyone, but we are not able to experience it. This is because of our likes and dislikes.We are in the grip of our ego and because of this we hold on to our likes and dislikes. In order to break away from the ego, we need to surrender ourselves to Sri Krishna.
All our actions and duties should be filled with the sweetness of love. It is that sweetness that transforms ordinary action into Krishna-seva or service to Bhagavan. Devoid of the sweetness of love to Bhagavan, action is mere labor. "Each and every living being in nature is part of the Krishna's body. Loving and serving Bhagavan is the true path to success .
Bhagavan Sri Krishna says in Srimad Bhagavad Gita 18.46 : " By worship of the Lord, who is the source of all beings and who is all-pervading, a man can attain perfection through performing his own work." - http://vedabase.net/bg/18/46/
