Seva, sadhana, satsang helps sustain life energy

Sattvic dhruti is that which sustains the mind, life energy, and activities of the senses - that which helps you to be steadfast in your yoga. Not like one day you do yoga and next you go for bhoga (sensory pleasure). Not like that. That which upholds your senses, your life is sattvic dhruti. 

Rajasic dhruti is of the type when I get results then I will deliver - This sort of mindset where your enthusiasm is related to some little reward is rajasic dhruti. It could be related to Dharma or it may not be related. Any work that is taken with the intention of getting results, such as fasting to achieve some results. What is God going to get if you fast? 

Tamasic dhruti is one who sleeps a lot - That is most important for them and nothing else. They are very fearful. You look at their face, they are always down and depressed. They are upset whether they are married or not. They are always regretful too. 

After 40 years of marriage, they think they should have married someone else. And one is unable to get of this negativity. Some people try to get out of it, but they are not able toof it. 

One who is lazy, gets scared easily. Then behind fear, comes negative thoughts such as who will cremate me when I die, who will take care of me when I grow old. Someone will complete the cremation rights. Man is mad. If you do not want to leave the madness, then be mad for that which has made all these things  not for the things made by Him. Then after this comes Vishaad: they think about what happened many years ago and get upset. A person who is enthusiastic and happy, will not go into Vishaad. 

How do you get out of Tamasic dhruti? Do seva, sadhana, satsang. Tamas gets converted to Rajasic and then to Sattva.
