Affection, attachment and infatuated love are all modifications of these alities. On account of delusion created by these three alities they are not able to break the worldly ties and to turn the mind towards the Supreme Soul, the Lord of the three alities.Avyayam Immutable or unchangeable or inexhaustible or imperishable. The Self is of one homogeneous essence. It has not got the six changes or modifications (Shad Bhava Vikaras) which the body has, viz., existence, birth, growth, modification, decay and death.
