Santhosha is the second of the Niyamas. Santhosha means contentment. Santosha means modesty and the feeling of being content with what we have. To be at peace within and content with one's lifestyle, finding contentment, even while experiencing life's difficulties for life becomes a process of growth through all kinds of circumstances.
The first of the five Niyamas is shoucha, which means cleanliness or purity. Shoucha removes negative thoughts and makes us healthy. Right from small things like brushing teeth etc., fixed rules and regulations have been placed, such that utmost cleanliness prevails in the society.
Asteya: Non Stealing
Asteya is the third of the Yamas, following Satya. Asteya means non-stealing. Asteya is the opposite-to take nothing that does not belong to us. Lack of gratitude can fuel an unhealthy desire for things that we don't currently have, such as name brand clothes, or the most supped up car.
Satya is the second of the Yamas, following Ahimsa. Satya means truthfulness. Satya means "to speak the truth," yet it is not always desirable to speak the truth on all occasions, for it could harm someone unnecessarily. We have to consider what we say, how we say it, and in what way it could affect others. If speaking the truth has negative consequences for another, then it is better to say nothing.
