It is most important that our activities be regular or, in other words, on a schedule. Everyone should chant his beads sixteen rounds daily without fail and follow the regulative principles strictly. These basic Krsna Conscious duties are essential to be performed regularly, and they will give you the necessary strength of spirit to keep always fixed up in devotional service. As soon as a devotee is regularly engaged in this way, always engaged in Krsna Consciousness, Krsna will reveal the whole spiritual science from within the heart of such sincere devotee.
