Vaishnava morality

The basis of Morality in Vaishnavism is founded on the simple understanding that to do harm to another person or yourself, either physically, psychologically, or spiritually constituted a concept called Pap. This term is often translated as sin which is defined in the English dictionary as an immoral action that goes against the divine law.

Piety, or Punya in Sanskrit, on the other hand, is considered to be any action that seeks to reduce the suffering of others either physically, psychologically, or spiritually.  The idea behind these is that quite obviously, pap is a catalyst for suffering, and Punya a catalyst for peace and possibly happiness.
The Vaishnava considered the degrees to which this concept could be extended and decided the highest Pap was forget the divine and the highest Punya was to remember him. To ensure this would be possible throughout life's trials and tribulations, the Vaishnava mystics took great effort to understand and describe the divine with as much detail, and hidden meaning, as possible, as to attract the minds and interest of the suffering people of this world and instill in them the catalyst for joy in a rather genius way.

The genius of this method is not immediately apparent for without an understanding of Sanskrit it doesn't jump right out at you.
Krsna is a conception of Godhead that is quite literally embodied in his names meaning.
Krsna means many things but the common meanings are black, the destruction of thirst, satisfaction of desire, all attractive, the source of all pleasure.
Wow! what a conception of the Divine. That which is the basis of everything as expressed by the colour black, that which removes thirst, satisfies Desire and bestows all pleasure.
Man has always struggled in this world to look for satisfaction and fulfilment only to discover the hydra-like nature of desire, wherein the satisfaction of a single desire results in the emergence of ten more. After waking up to this scary reality and realizing that you've been carrying on with this endless mission without really considering its feasibility, as everyone else just seems to be playing the game, why would you question it?
The Vaishnava prescribed a transcendent and eternal antidote to suffering. A simple remedy for sin that would be so attractive, and so seductive that it easily took root as the dominant form of religious belief and practice in many parts of India for the past 5000 years at least and continues to grow even in western countries today.
Krsna is not just a force or energy,  nor some form of alchemical magic, or ecstatic trance because he exhibited human-like features. After all, how could Krsna satisfy all desires(which include human interaction, kinship, love, and romance) if it was not manifest in humanlike form? If Krsna was carefully understood he opened up the doors for understanding behaviour moral responsibility through a process of cleansing perception, egoistic tendencies, and the reduction of harmful and hateful emotions.
It is for this reason that Krsna is considered in all Sastras to be the height of all concepts, the embodiment of the pinnacle of all attributes, the basis of reality, the original person, and the supreme personality of godhead. Although sometimes referred to by other names such as Brahman, turyatita, pramahamsa, sunya, Narayanaya, Visnu Buddha, Vasudeva etc.
Despite his ultimate supremacy, he exhibits himself in the simplest, and most charming, and approachable way. He is like us, near us, and within us...Remember the highest good, and use that as your beacon.

Vaishnava morality, although full of lifestyle recommendations, many forms of ritual, asceticism, and meditation,  are all predicated on the above goal.  These can sometimes be sadly misrepresented or misinterpreted and become catalysts for the opposite goal.
Morality is not an excuse for abuse, bullying or fear mongering, manipulation, or egoistic ambition.
The application of these routines, rituals, and lifestyle restrictions are intended to be applied to oneself and oneself alone. The guidance of a qualified teacher is of utmost importance, but your own conscience and reference to relevant ancient wisdom, can and must suffice in the absence of such direct guidance.

Please, Always remember Krsna and never forget him.
