There are many roads leading the bazaar, so in the same way there are many 'dharma', which everyone suits an individual, he follows it. There are as many thoughts as there are people and as many thoughts that many dharmas.
What is the best dharma?
All the roads of the bazaar are good. The one that suit us is the best. The same applies for dharma. All the dharmas are good. No dharma is wrong. The dharma that is convenient for us is the best.
What are the main attributes of dharma?
Dharma has four main attributes.
Sacrifice: To renounce worldly and materialistic attachment. Penance: Self-mortification in order to attain God. Mercy: God exists in every single particle and atom (molecule) in this universe. With that understanding one must have mercy and compassion for all. Never harm anyone. Try and assist others to the best of your ability. Truth: Always speak truth. These are main pillars of all dharma. To imbibe and practise them in life, the paths are different.
